i have an 1988 arctic cat cougar 500 F/C and i finally got everything built and it revs mad high!! i rebuilt the carbs but nothin changed. cleaned everything and it wont work right. it starts it just revs so high. any ideas???
my sled was doin the same thing.. I sprayed carb cleaner everywhere when the sled was running and didnt find any air leaks... Ended up being my throttle cable was to tight, and makin it rev high. So I adjusted that properly, and adjusted my idle accordingly, and now its alot better
well i did have the carbs loose so i could pull them off without having to keep loosining them up so that could be a problem... but the slides in the carbs only shut half-3/4 of the way so they stick open and it revvs really high... idk what to do! i looked atta throttle cable today and it costs 115.00!!! so im not dumpin that into it if its not necessary...
its at my buddys shop and we messed with it last night.. was told it was the diaphrams but theres none on my sled obviously lol so another guy told me to use steel wool but i dnt want to mess anything else up!
If the throttle cable is too tight, it will not allow the slides to close properly thereby causing the condition you are experiencing.
I suggest that you address this before trying to run it any longer.
loosen the nut on top and bring the slides down till you have like a #2 pencil in there. thats about where it should be not half way down. and look to see like RJ said about the needle being bent.good luck
no he said his slides are only half shut so i'd say he has slides. also mine does that also when i first take my choke off also. i think it is normal cuz all my sleds do it. but i have mine to idle at a grand.
