just cleaned the carbs yesterday. first time i ever did that. I pulled the pilot jet but not the main jet also pulled what I think is the air screw next to the pilot jet.all clean I screwed them all the way in not to tight. fuel screw is at 2 turns out. but now it idles at 3000 rpm when warm. If I pull the choke it goes down to about 900 Rpm.runs fine down the trail though. Any suggestions on how to fix
 
hey, low mile

whats the odds, of the two of us, buying the same year sled, and neither one of us, knowing what where doing? LOL!!!!!!!! no insult, Im only busting on you...hehehheeeeeee ;)!
 
and check your throttle cable play.This season for me I am getting high idle on both my sleds. Carbs are totally cleaned,both have stock pilot jets,and fuel screws turned out the right amounts..but fast idle remains.If I turn the idle screws right down and adjust cable...it works...almost...But when it comes to start next day...sleds start and the damn idle is way to low to keep engine runing,have to hit the throttle to speed it up until engines warm up..then good.I am stumped on this issue also.Everyone says..must be your pilot jets are plugged..clean carbs.Well have done that like you(unless your idle screw nweeds to be turned down)and fast idle almost always re-appers.
 
The idle screw is the slotted screw near where the throttle cable attaches to the carbs. It's pretty self explanatory when you see it.
 
but your are talking about the 96 model,still should be easy to locate that screw.Follow your throttle cable to where it pulls the cam which in turn operates the fuel supply to the carbs.That screw in usually against that cam.
 
I turned it down. right to 1600 rpm could that have been because one fuel screw was at 2.5 turn before? and as to how i couldn't see the screw is I didn't know what I was looking for.
 
thanks for the help and the patience with me the newbe. I guess I'll let it cool down and try tomorrow morning and see how it goes.
 
One more thing lowmile, if the idle creeps back up, hit the throttle real quick at idle and let it slap shut. The pivot on the throttle lever could be binding. Also, take a look at what moves when you give it throttle. You can manually push a lever down to make sure it's closing all the way at idle. My guess would be that it's the throttle lever, throttle cable or choke cables. It's possible that one of the choke plungers is getting stuck open but that usually causes the motor to bog down.
 
just let it run for about 10 minutes started to idle around 800 turned it back up. I would give it throttle and it would stay around 2000 and slowly come back to 1500-1600. I guess next would be let it sit over night and try when it is real cold.
 
Check to make sure the cable is seating all the way, at both ends. It's possible you've pulled the cable out a little while working on it and it's hung up on some unknown 'pain in the butt' point.
 
just checked throttle cable and choke cables all seems fine. choke cables are tight in the carb and pushed all the way into the little boot. Started it and all seems fine for now. I just don't want this to affect performance I am just after reliability.
 
Check where the throttle cable screws into the bracket on the carb rack. It is possible that the gap was changed and the throttle is being pulled slightly. Check you plugs after you warm it up and make a couple mid range passes to make sure you a burning good and not to rich or lean, better rich the lean however. Especially if it is warm as the lean out when it is cooler.
 
I thought about that gap for the throttle cablebut if it mover it would have been minimal. Do you think it would hav made a 1000 rpm difference and I'll check the plugs tomorrow after work.
 
Started the sled this morning. 2 pulls with choke on 3000 rpm turn choke off about 2500 rpm. Warmed up about 5 minutes went back outside it was at 1600 rpm. looks like it running fine now. I'll see tonight when I take it out and then check the plugs. Should I look for anything else on the first run?
