Really you lost that much top end. How fast does yours go, according to the stock speedo. Mine will hit 53-55. I to have the 99 i still Have my stock 26". Maybe the cre8 would be worth the try

Andy,

The CR6E was my stocker, I switched to the CR8E and got a noticeable power boost in the summer.

The reason you noticed a power drop was that the colder weather has made your motor run lean, so the spark plug is not right for the jetting.

 

Cowboy,

To drain the float bowl you don't have to remove the hole carb. ON mine(I have a differnt carb) there is a screw on the right side that opens the valve to the float bowl. I have to attach a hose to a little fitting so the fuel doesn't drain on the motor. Yours is probaly differnt. Check your owners manual, I think it was in mine.

If you are gonna remove the carb at all do it when the gas tank is off, thats the easier way.

What you could do is drain the carb, remove the gas tank and dump out the gas(do all the oil changing and other crap first). Then PUT the tank in place(don't bolt it down) and put about a gallon of fuel in it. Then run it. See if you can get it to idle normally.

If not, then try to disassemble the carb and clean it.

 

girthyguy,

Since Arctic Cat recommends this spark plug I don't think he is in any danger of damange.

Did you adjust your throttle cable yet? I did to mine and noticed alot better throttle response. I don't know about topspeed yet cause my bearings and toe in REALY slow my cat down so I can't test it yet.

 

My stock plug was a 6 as well. I switched to the 8 due to some advice from several guys on here, and did notice a slight power gain in doing so. So, should I put an 8 back in now, or go with a 7??? I believe the 7 used to be the standard plug, from what my dealer was saying, until they bumped it up to the 6 in '98 he thought. I was going to change the plug as well, but forgot to buy that for some damn reason-it was on my list with oil and filter, somehow forgot it.

Anyway, Boner, you were right, my carb was full of water. I took it out of the machine, then pulled the top gold colored cover off, figured that was wrong, so I put it back together. Then, pulled the smaller triangle plate with 3 screws in it off, had some water fall out of it, wasn't sure if that was the right place or not, so I put it back together. Then, I pulled the thing nearly in half, ended up stopping mid way though, and put it back together as well. Like I said, I don't know jack about carbs, so I was getting a little worried about what I should and should not be messing with. When done messing around, I put it back together.

I also took the tranny cover off, the side of the tranny as well. Belt looked great, just like new, but there was about an inch or so of water in the entire bottom of the housing. That would explain the motor running, and the machine not moving very well-belt slippage for sure here and also, the very first time ever.

Also, changed the oil and while I didn't find much, there was a traceable amount of water in there as well. The plug was black when I pulled it out, but like I said, I'll be putting the new one in tomorrow after I make a special trip just for it, as like an idiot, I forgot today. Also cleaned the air filter real well, drained the gas tank and installed some heat in with the fresh tank. After putting everything all back together, I just let it set. The air filter isn't dry yet, so I'll wait and try to start it tomorrow after the new plug goes in. Oh, changed the oil filter as well.

Is there a specific reason the carb vent line is located so low on the engine? I can see how the water easily made it's way up in there, so I re-located it up above, closer to the air intake, but kept it turned down just for good measure. Oh, also cleaned and put some oil near/in the steering column/bushings like you recommended, to prevent any possible squeaks later on.

Anything else you can think of before I start her up tomorrow?

Thanks again for the advice!

Mike

 

Cowboy,

Just look in the owners manual for the carb drain, it should be in there. The drain for the fuel bowl will be somewheres at the bottom of the carb. I bet there is water in this bowl.

 

Boner,
Your right about the throttle cable. Its usually a pretty standard thing to do, because the cables always stretch. Its like if you by a new bicycle they always recomend you bring it back in after so many miles so the can adjust the cables do to stretching. There is one thing about AC from all of the years riding there snowmobiles, ac is the worst out of box sled. But with a little bit of dialing up the clutches and rejetting the carbs you cant beat an AC. I havent really tinkered with the fourwheeler performance wise. But I bet with a little work it will surprise you. Atleast thats the way there sleds are.

Boner:
Thanks for the replies, wish I would have seen them earlier today! The bit about the manual is my problem-see, I normally keep it in that space in the bottom of the seat in a zip-lock bag, that way it's always there should I need it in case of an emergency sometime. Well, I went to grab it, and it's not there. For the life of me, I can't seem to find it anywhere.

As for your directions, that's pretty much exactly what I did. I drained the oil first, then just left the plug out. Then, pulled the old oil filter, put the new one on. Next, took apart the tranny and drained it, left that plug out, and the outer case off. Then, pulled the gas tank off, and pulled the carb up and out through the top. I played with both the top and bottom, but didn't adjust any screws on it at all. Hey, what is that black cable/wire thing that has a *** attached to it on the bottom right side of the carb? It's about 3-4" long or so, and has a **** of some kind on it, looks like you would turn it to adjust something??? Like I said, I can't find my manual anywhere and don't know where my dad put his, so I can't exactly look it up.

Anyway, I put most of it back together, with the exception of the side panels and airbox. I'm going to change plugs tomorrow, and have also been re-wiring my reverse lights, and mounting a different switch in a new location. After I get that stuff done, I'll fire it up, see how she sounds.

Anyway, thanks again for the info, sorry to bother you so much lately!

Mike

 

Cowboy,

Sounds like you are describing the choke cable to me, but I could be wrong.

BTW: It's no bother at all, I have fun doing this kind of stuff. Why else would I be here? Besides, did you do me a favor by giving me those measurements for my future snorkel???
