Not sure if this helps, but I found out that Johnson recalled their mechanical fuel pump. They told my mech. to replace it with an electric fuel pump and that this was the only solution. Mainly because of recall, and obsolete parts. This is after carb cleaning, throttle body replacement, fuel pump diaphram replacement. Soooo. took some time and money, but im now back to smooth sailing. See previous reply for my original problem.

Thanks and Good Luck!
