My sled has been giving me fits all year. here is the latest problem. It idles at 4 grand and will only come down if you flip the choke so I know its a lean condition. But when i do the whole pin it across a field and kill it and check the plugs they are good. So its only lean at idle and possibly in the bottom end.

I guess my question is what tweeks could i do to remedy this problem. I am running short on patience with this thing.

Any help is appreciated.

You can turn the idle down using the screw that is on the carbs.

Thats already completely off the lever arm that it pushes down so it shouldn't even be able to idle.

These sleds are notorious for this. Bigger pilot jets or try turning your idle mixture screws out a quarter of a turn. Make sure they are out the same number of turns from lightly seated. Were these carbs set up for a different elevation?

What gets me the most is it ran fine last year. This summer i took the motor out and everything to do some detailing and I put it back in and it wont run. I am sure i did everything correctly to as I have had lots of these sleds apart with no problems.
I'm thinking its going to a dealer once I have the money for it. I'm sick of dealing with it and throwing money at it and not helping.

Try spraying some carb cleaner around the carb boots and crank seals to see if that changes the idle. If it does then that means you have a crank leak somewhere.

Got the same problem, no idle adjustment have sync'd the carbs many times idles at 3000RPM. adjusting pilot screws tonite see what happens.
