Does this sound like carb problems? "Motor runs fairly well, but does have some problems 1) Engine speed fluctuates after running for 20-30 minutes 2) Motor will often stall if trying to maintain a very slow speed, such as within a marina 3) Smokes from under the engine cover when first starting, and for 5-10 minutes while engine is warming up."

It seems this might be something a good carb cleaning or kit would take care of. I know it's hard to diagnose off only this, but if you had to guess...

Re: 9.9 Yamaha - Carb Problems?

I think the first two might be carb, but the last might be a leaky gasket at the power head? I think I am going to pass on the motor. Though the $275 price tag for the e-start 9.9 is tempting....
