With that mainjet it must be an early build like I had, open the mixture screw up more, this allows more fuel through the pilot circuit (it controls fuel not air on this carb) The needle clip should be in the 5th (bottom position)

 

Well that's good new's to hear , i had a 93' Suzuki LTF4WD 300 KQ that i sold to my brother in feb. 2006 after i bought a new AC 400 ; and before i sold it to my brother it started running ruff and bogging down and stalling when you would come to a quick stop !

I was on the verge of buying a new carb kit untill , i found out that the pump diapharm didn't come with the kit ; and it was really the diaphram i thought needed replacing !

Because i had removed the carb and when me and my cousin were riding when it was only 4 months old , he had gotten some gas with trash in the tank and i had to remove the tank and carb ; and wash out the tank and carb and while i was at it i put a clear inline fuel filter !

And i took the pump apart to check the diapharm , so that was the reason i was going to get a new carb kit ; the KQ would do the same as the Hawkeye when i would pull the choke a little ; it would increase the rpms !

And make the quad try to run away with you , and i had to turn the idle speed down to stop the engine surge ; the way it was doing this that got me to thinking about jetting the carb !

Both my old 86' Honda TRX350 Foreman 4x4 , and the 93' Suzuki LTF4WD 300 KQ when going riding in the mountains ; i would have to increase the idle speed and lower idle speed when i rode in the mountain's for them to run right !

It was getting worse every time i rode it , increase idle speed to keep from stalling ; then lower ildle speed to stop the surging !

It was only after i sold the KQ to my brother that we found the problem , it was the loose choke cable that made the KQ run so bad ; after my brother removed the plastics and cut all the plastic tie's and rerouted the cables and tightened the plastic nut on the choke cable into the carb that fixed the problem !

And keep us informed on the Hawkeye when you're finished with the job ! ......

 

OneCar Here's one thing everyone hasn't ask , and the reason nobody else has ask this question is it might sound like a stupid question to ask ; But i'm not sure about this but does the 2006 Polaris Hawkeye have a compression release valve !

Like some atv engines do , if you're not sure maybe someone else will know ; my 2006 Arctic Cat 400 FIS Auto has the Suzuki Powered 376cc Engine and Suzuki Duramatic Belt Driven Clutch !
And it has a compression release valve to make it easier on the starter motor , and the person trying to start it with the pull rope ; like i said i don't know much about Polaris Engine so i don't know if they have a compression release or not ! ...............

 

It does have a decompression mechanism on the camshaft, if that's what you're talking about. Most four stroke motors do though...

 

OneCar I did an edit on most of my reply's they were to long , i'll try to make this one short , and yes i mean't (a decompression valve ) the reason i ask is because my cousin rode dirt bikes before 3 wheelers and 4 wheelers were around ; i know for sure the one with the decompression lever was a Yamaha !

I don't remember the year , just late 60's or early 70's it was a Yamaha street or trail and it had a trigger type lever mounted on the left handle bar ; we were riding together once and we switched bike's about a mile from his home !

I remember i squeazed the lever not knowing what it was , and it was like hitting the brake's ; and the bike came to a complete stop !

I didn't know what happened , but when mike caught up with me he ask me why i stopped ; i told him i squeezed the lever and he said now you'll have to tow me home !

He told me the lever i squeezed was for engine compression braking , and it was stuck in the open position and he didn't use it ; i had to pull him home with a rope he carried for towing when someone broke down !

I told him he shouldn't have it hooked up if there was something wrong with it , when we got back to his house he unhooked the cable so it wouldn't happen again ; i liked the idea of the way it worked like atv's with engine compression braking !

The atc's and atv's ( Yamaha's and Honda's ) are what he ride's now , i thought that was a good feature on the dirt bike's if they could get them to work without sticking ; so you didn't have to use your brake's as much !

When you were asking if the engine was suppose to turn so easy with the spark plug in , i thought about the Yamaha that mike had back then ; and that if the Hawkeye had the engine compression braking it might be the decompression valve sticking !

When i got my 2006 Arctic Cat 400 FIS Auto the first time i rode it up some steep hill's where the Power Co's. right of way , the AC made a rattling noise ; and i posted a question about what could be making this rattling sound in high gear !

Someone thought it might be the decompression valve making the noise , and someone else thought it was the plastic skid plate's rattling ; but it turned out to be lugging the engine before the ring's were seated ! OneCar let us know when you get the Hawkeye going , i would like to hear how it sound's when you get it going right ! .................

 

Mine older Yamaha Exciter 570cc snowmobile has a decompression lever on it...............You need it if the elect. start don't work!!............Caper............

 

Just a thought but have you checked the Spark Plug and made sure it hasnt been dropped and the gap closed on it, You may have but lets make sure ive done that before and it wouldnt run past 1/4 throttle

 

caper That's what i thought , ever atv i've owned had a Decompression valve of some type or the other ; my old 86' Honda TRX350 Foreman had a Decompression valve that was auto activated by the kick starter !

The 1993 Suzuki LTF4WD 300 KQ had a trigger on the right side of the Jug/Cylinder , and you had to **** this trigger everytime you used the pull rope to start the engine !

And when i got the Honda i had to replace the starter So i took it to the local Honda Dealer i had known for over thirty yrs. and i thought he would treat me right , by the time i got back home the phone rang i picked up the phone ; it was the Dealer with bad news !

The starter couldn't be rebuilt he said the armature was burned up , he told me a new starter would be ovver $200.00 and ask me what i wanted to do ; i told him i was a bilaeral amputee with no legs below the knees and i couldn't kick start it so put a new starter !

And i told him to only put a starter and battery , because i had just changed the oil oil filter and cleaned and reoil the air filter , when i went to pick up the bill was for $287 +tax ; and when they were loading on my truck a young boy said i changed the oil and oil filter and adjusted your brakes !

They had done a complete a tune up and serving even though i didn't ok it i paid the bill ; and started home and when i started to unload the quad !

The first thing i noticed when i was driving it off the truck was a puddle of oil in the truck bed , i got a grease ray and wiped all the oil from under the skid plates ; then i put my finger on the oil plug drain bolt and there was oil on my finger i wiped the oil off again ; and put it on the drain bolt again and it had oil on again !

But i thought the kid didn't tighten the drain bolt , so i got my socket set out of the shop and put the socket on the ratchet and started to tighten the plug ; and it started to get tight then loose again the kid had stripped the threads in my oil drain hole !

So i called the Dealer and he said the drain hole was already stripped when i brought it in , i calmly told him the kid stripped the threads and he for going to fix it ; The Dealer told me he would rethread it for $50.00 + tax i told him again that he was going to fix it free of charge or i would sue him if he didn't and he just hung up on me !

Sio i took the drain bolt with me and went an Industrial supply store and bought a $49.95 Heli Coil set and special $19.95 Titanium drill bit , then i went home i had already drained the oil ; so i coated the drill bit with 80*90* weight gear oil and drilled out the drain hole and tapped the threads !

Then i poured kerosine and acetone through the oil fill plug , flushing the metal filings and gunk that might be in the engine ; then i installed the Heli Coil and put the drain plug in and tightened up the plug !

Then refilled the crankcase and installed a new oil filter , then i went to my shop and started filling out a work order ; After itemizing the bill it came to a total $168.97 !

Then i went to the Dealership went inside the showroom and handed the owner the bill with my letterhead , i thought for a minute he was going to have a stroke when he read it out loud ; after the shock wore off he said i'm not going to pay this much for something that you did to your drain hole !

He said he didn't even charge that much for rethreading to a larger drain bolt , i told him i don't just retap thread's that will strip again ; after the next few oil changes and that i use Heli Coils when fixing striped threads !

But he still refused to pay saying the drain plug hole was stripped when i broght it in ; i told him if the drain hole threads were stripped when i brought it why didn't you tell me when i came to pick it up !

He didn't have an answer for that , but he kept telling me he wasn't going to pay that much ; so i told to look at the card attached to the work order ! He began reading out loud , Joepth E Willaid Jr Atty At Law , and after he finished reading the card he told me he would me give me $50.00 take it or leave it ; i got out my cell phone and starting dialing the number and i had is set for driving mode !

As soon as the heard a womans voice say , Joepth E Willard Jr Atty At Law he told me ok i'll pay you the money ; and this was one of the tightest Penny pinther i had ever saw but he paid up this time ! ...........

 

If he said the threads were stripped when you brought it in.................You should have said how do you know? I didn't even ask for a oil change and filter anyway!!!!....I came for a new starter!!!

...LOL......Caper................

 

You're right caper and at the time i was very upset about the stripped drain hole , and i did ask him how did he know the drain hole thread's were stripped snice i only came in for a starter rebuild and a new battery ; iif it needed a new battery !

And his reply was that they alway's gave a free oil and filter change to evey new customer who spent over $100.00 as away of saying thanks for your bussiness !

I ask him why did you change the oil when i told you that i had just changed it the day before i brought it in for the starter rebuild , and to check the battery to see if was bad to replace it ; he didn't have a answer to that question !

I was just surprised he didn't charge me for a new battery ; because a few day's later the battery was dead and wouldnt take a charge !

My guess is he knew or the kid told him about strippng the threads , and he didn't want me to know it was done by one of his high school kid's who he only had to pay minimum wages ; because he was a tight wad when it came to money !

That's why i thought it was strange , that he had told me about any such policy on giving a free oil change ; to a new customer who spent a $100.00 at his shop !

And i had forgotten the time he tried to rip off my eldest brother on a 1972 Honda CB450 motorcycle , that my brother took to his shop to have them to put 2 points and condensors set's ; and 2 carb kit's to tune up his bike (he had the parts because the original owner gave them to Roy when he bought the bike from him ) and he was told it would cost $35.00 + tax !

But when he went to pickup the bike the only one there was the Dealer's wife , everybody else were out to lunch ; Roy ask her if his bike was ready and she started to look for the work order !

When she found it he ask how much do i owe , she looked at the work order and told Roy the bill was just under $850.00 ; she said that's what the total charge was !

Roy kept telling the woman there has to be a mistake , that the Dealer told him it would be $35.00 + tax ; and that there had to be mistake !

The Dealer's wife showed Roy the work order , and the sales receipt , he said when he read what they had done to the bike ; on the work order was for cleaning and rebuilding the carbs ; and installing tune kiks + labor for the tune up and a new 1975 750 Twin cylinder Engine !

He told her that couldnt be his Motorcycle because his was a 1972 CB450
Morcycle ; not a 1975 CB750 bike and there had to be a mistake and they got the bills mixed up some how !

But the Dealer's wife looked at all the work orders , and said a 1972 Honda CB450 with his name on the work order ; and on the Bill of Laden was for Roy's name !

Roy was getting mad by now and he was just about to go the Finance Co. where he Financed the Bike at , and tell the guy over loans dept. ; that they would have to repo it from the Honda Dealership !

And just before he started to leave , the machanic who worked on the Motorcycle came in the door he ask Roy if he was the one who owned the 1972 Honda CB450 and Roy said yes it was his Motorcycle ; the machanic ask Roy how much did they charge you ?

Roy told him that the bill was just under $850.00 , then the machanic told Roy all he owed was labor on installing the tune up kit's and cleaning and installing the carb kit's ; he told Roy and the Dealers wife all Roy owes is $35.00 plus tax for labor !

She said she didn't know anything about it , that all she knew was her huband had everything itemized and he couldn't get it back untill the bill was paid in full ; and they would have talk to him when he get's back from lunch !

Roy said they had to wait about an hour before he walked in the door , and when he came in and saw Roy and the machanic waiting on him his face turned white as a sheet ; and first the machanic started calling him a theif and liar ; and a few other names i can't say on the forums !

As it turned out the machanic was going to have to pay for a new 1975 CB750 Twin cyclinder Engine because ( They couldn't find another 450 engine antwhere in the Tri Sate Area ) , so they had to put a new 1975 750 Twin Cylinder engine on the 450 frame ; And because he failed to check the oil in the CB450 before starting the Engine and giving it a test drive ; and it slung a rod taking out the top and bottom end of the engine !

Roy asked the Dealer why he changed the oil and oil filter , after he told him the oil and filter were changed a day before he dropped it off ; and the machanic told the dealer he didn't change the oil !

Come to find out that the Dealers son had changed the oil and filter , and didn't tell the mahanic he didn't refill the crankcase with oil before they took their lunch break ; after hearing this the machanic gave him notice to look for another machanic and he told the Dealer he wasn't paying a penney for his son's mistake !

And noit to mention the fact that the Dealer was trying to double charge for the engine , In the end Roy only paid $37.50 for a new 1975 CB750 Twin Cylinder Engine mounted on a 450 frame ; and the Machanic told Roy the Dealer had to give him a new set of exhaust headers and pipe's for the 750 engine )He told Roy that the old headers and pipes from the 450 would cause to much restriction to cool the 750 Twin's engine whitch would cause burnt valves !

Roy said the Dealer had ordered a set of pipe's for it and they would be there next thurday at the least , and the Dealer said if the pipes aren't here by friday he would remove a set from one of the 1975 Bike's he was expecting to come in next friday ; and he told Roy that he would give him a good deal on the labor for installing them hisself !

But when Roy called the next thurday he said that Honda didn't have them in stock yet because they were for the new 750 Twin that just came out , and it might take longer than he thought it would be ; Roy ask him when he could expect them he said it might take a month or more but he wouldn't forget him he wound be the first one on the list !

Roy didn't want to wait that long , so he went to the Grand Opening of the New Kawasaki Dealership where they were suppose to be the showing the new lineup of the Kawasaki's ; so when Roy came over to my house he told me come look at his new bike !

I thought he was talking about the Honda , and i went out to see this Brand New 1975 Kawasaki 900 4 cylinder motorcycle , i ask him if he traded in the Honda on the new Kawasaki and he said no way ; and he ask me if wanted buy the 450 i ask how much and he told me $450.00 on credit $20.00 a week i said yes and when we get our income tax refund check i'll pay the rest in full !

I ask Roy about the pipe's and he told me the Dealer said they weren't in yet , and it might take a month for them to come in ; i told him about the promise the Honda Dealer gave him about the pipe's !
I told Roy to sign over the Title to me and i'll take care of that , as soon as he signed the title to me i got him to ride me out to Dealership just in time as the Dealer was uncrating one of the New 1975 750 Twins ; and i went around back and told him my brother want's his pipes !

The Dealer said they haven't come in yet , and i told him it could be a month before they start shipping part's for these new ones ; and i reminded him of the promise he made to my brother !

You said if they weren't there by the time the new Bikes came in you would take them from one of the new 750's , he didn't like it but he took the pipes from the one they were uncrat
ing and gave me all the fasners for me to hold then handed me the headers and the rest of exhaust pipes muffler's and all !

Then he told me to bring the bike around to shop and he would get someone to install them , then i told him it was still at home and i was going to do the installing myself ; then i could see he was mad he told me to tell Roy if he let me install the pipes he woulnd't be responcible if i f my made a mistake !

And i told him that i would be responsible , because i just bought it from Roy ; and when we got home it didn't take less than an hour when we were ready to ride ! That's why i say not to trust just any Dealer or their machanic's when they say this is what you need , there are just to many of these machanic and Dealer's out there that sale you anything to make money ! .........
