I have been trying to figure out my poor running condition. I decided to go into the carbs again and I found that one of the two screws that hold the fuel pump together is stripped out and for sure was not getting a good seal on the gasket. Maybe an air leak. Would this cause hard start, feather the choke to get some speed, rough idle. What do you think. Going to find better screws to day to get that tight. I think these are the two screws that were at one time tamper proof. Before someone got in there.
