Default Re: Driving & then COUGH COUGH & Died..10 min later start & Fine..& Died again.

Although I have a similar problem, it's not as severe. I'm crusing along with the mixture around 1/8 open and going about 45 MPH. Then, power loss and carb backfire. I open the mixture to 1/4 and then it gets better.

Later,I can return to 1/8 open O.K.

I have cleaned out the sediment bowl, but that's all.
The gas shutoff valve is hard to turn, and it sounds like I need to drain/check the fuel system.
