I have a 2001 Yamaha Kodiak 400 Ultramatic and I’ve been having some issues with the idle.

The idle increases as the motor warms up to a point that it is racing and I cannot put it into gear. I have to juggle the choke and the idle adjustment screw to be able to get it at the right base idle so I can leave it alone on start up, and once it’s warm, I have to fiddle again to be able to put it in gear.

I replaced the idle adjust cable last year, but this problem is older than that. I also gave the carburetor a brief clean from the outside. Nothing has changed.
