new problem i started my bike tody and it will not idle properly if i gas and let off it will not return to idle it will idle high and then go back to idle

 

check the diaphram or actually it sounds like the butterfly is stuck due to the cable

 

i double checked the diphram,throttle cable,and everthing else i could think of but the thing will not run right it feels like it has no power and it first gear it will pop and then accelerate and it will return to idle sometimes and sometimes it wont should i get a bigger jet or what should i do

i have a 175 jet and i have the clip set at the second postion on the needle im all out of ideas any help would be greatly appreciated beacuse im taking the bike out tommorow and want to see if i can get it runnig correctly thanks.

that really sucks some1 else is having a prob with their rectifier or a simple thing as the choke being on could be causing it I am just about out of ideas I would think that you could just try messing with the idle and see if that helps any check to see if your headers are tight I had a problem with them being tight and the gaskets were bad and it was backfiring

 

The pilot controls the idle so check that and see if its clogged. If not go bigger on it. Check your air screw also. Screw it in all the way and then out 2 turns and see if that makes a difference. What did you do to the quad or has it ever run good with this carb?

 

i have the clip positioned in the 2nd grove from the top is this no.2 or no.4 i think i have it set to lean

 

needle is too lean, you are on the 2nd groove, otta be on 4th.
when you let off the throttle and it pops it is indeed a lean pop. this is commonly caused from mal-adjusted idle mix, however your needle being so lean also causes this so set the needle correctly and then see how it is before you screw with anything else.

the problem with it not wanting to return to idle is often times due to not enough throttle cable freeplay. the cable may be staying tight and not totally relaxing, you need to adjust the cable slack adjuster under the rubber boot next to the throttle housing on the handle bars such that the throttle lever moves about 1/4" before it actually starts moving the carb throttle. this way when you turn the bars and flex the cable it does not change the idle.

 

Also make sure your cable is lubed.I just spray some silicone spray down there.
Mine was sticking and i tore the carb apart before i figured out i had a dry and
dusty cable.

 

im still having the popping problem and the bike doest feel as strong as it did when it was stock ive only driven it 5 or 6 i changed the clip to the no.4 position but im still having the problem with it.


should i move up to a 180-185
