Re: Yam 9.9 carb question
Thanks for the response...yes, she runs rough and stalls at idle; my mechanic suggested I remove the carb because, he says, 95% of these problems are due to carb, which, he says, is because they don't tolerate the ethanol blend. Since I can't get the motor off the boat (it's in a well and requires going under the boat to remove the prop), he suggested just bringing in the carb. I tried all the obvious fixes like plugs, new fuel filter, new gas.
