Re: Pop and Bang

ahhhh your added info has me thinking either a big vacuum leak at the carb base or even at the manifold to head connection. if all that looks good you might crank the mixture screw out a full turn or start with it all the way in and turn back out 2.5 turns. most carb rebuilds do this, there is a chance its super lean right now
