Its runnimg like its missing on one cylinder. I replaced the spark plugs and coil as well as the the carb. It was running with a little too mich oil, so I drained some of it out hoping that would keep it from burning whatever would cause it to burn a white smoke. I allso repla'ed the intake/exhaist m!Ifold gasket. Any ideas what the problem is?

If you are getting white smoke from the exhaust, chances are you have a bad head gasket. White smoke is usually from coolant burining in the combustion chamber. Check to make sure the coolant isn't mixing with the engine oil and oil isn't getting into the coolant. Also, you should check engine compression to see if there is a weak cylender.

LEt me know if you have other questions.

I was thinking it was either that or a bend/pinched fuel line, since it has the steel lines from pump to carb.

It could be a fuel pump problem, but if you have white smoke, chances are good it is a headgasket.

Well, once I got the gasket replaces I notices it was trying to start ang would backfire. The carb would also pop and it seems like a grey smoke would come out of it. Any ideas? Maybe spark plugs or wiring?
