1998 Yamaha 9.9 4 stroke idle problem

The motor runs fine with throttle, but will not idle. Is there an idle mixture adjustment?

Thanks

You have a gunked up carb - very common and annoying - as you have to remove the carb and have it "cleaned" - but then it will do it again and again.

See my post - They should put wing nuts on these carbs
