Re: misfire

Did you set the dwell? is 6degrees correct for your engine? What engine is it?

What about fuel filters? What about the fuel itself?

Ayuh,... Now rebuild the Carb,... I bet it's got a boatload of Crap in it...
And,... You probably have 2 fuel filters,.. 1 in the fuelpump,+ 1 in the carb...
