I have a couple of PT giving me a similar problem. They have modified carbys they start straight up rev as they should, idle fine but then they will just stop. Prime them a couple of times and they repeat the procedure and then just stop. The tank breather is clear, fuel flow seems fine and the main jet filter in the primer cap is clear. I have modified a couple of carbys and they seem the same. I'm just wondering it it may be a lower seal issue. Any thoughts before I just swap the motors out and put these in the future repair pile?
