Re: Vapor Lock Issue
I agree with John on this one, go after the coil. I have run my 1980 2414 without the fuel pump with out any issues. The tank is a bit higher than the carb, so you can never empty the tank. The 1965 2412 with the L shaped tank was higher than the carb and it didn't have a pump, never had any issues. Learned this the HARD way. Always put a filter between the tank and the pump and another filter between the pump and the carb. On an old pump, it flakes small bits of rubber and not let the float seat and causes flooding.
Coil getting hot will open or it will sputter and loose spark, sounds like it ran out of gas, then open. Let it cool and it starts right up, runs fine. Next time it happens and you are running battery/coil ignition, feel the coil and see how hot it is.
