Something else to consider. Try backing your idle screws out just a little to give it alittle more fuel at idle. Your strictly on the idle circuits at idle obviously and if you set them when the motor was cold they may not be rich enough. Back them out a 1/2 turn and see that that does.

Just a thought.

Understood....but that will have no affect on the stumbling under acceleration. I have been searching for instructions on replacing a manual fuel pump with a electric, but am finding no good info. I figure I will have to install a "T" in the fuel line right before the carb., and run a secondary fuel line back to the fuel tank, but how do I get the fuel back into the tank? I cannot imagine just drilling a hole in the tank and plumbing it in........and removing the tank to have a fitting installed seems like way to much work.....must be a simple in between method.

F-man, forget about it, the return line that is! After the fuel regulator run a pressure gauge and after the fuel log you cap the line. That's how mine is set up.

I see Z-link was typing at the same time as I was AND he has a more precise explanation!
