After trying everything to get my 1985 Force 85 to run reliably, I am now thinking of adding a 2-4 psi electric fuel pump. The question is, where should I install it? Should I put it between the tank and ball ( I have heard that these pumps are pushers not pullers ) or, do they pull enough to install it inside the engine cowl as a header pump for the diaphram?
The problem I am having is my engine goes lean periodically and I have to pump the ball after it loses its prime. During the first hour of operation, you have to do this often. After that, it happens periodically when I try to accelerate. Some times it will not do it for a couple of hours.
Compression is 150 on all three cylinders, plugs were changed twice, carbs torn down cleaned and reset, all fuel lines and return lines changed, all tanks cleaned and new fittings installed, fuel pump changed twice, check valves changed once, fuel pump orfice holes cleaned and blown clear, stator windings, cdi and coils checked and eliminated.
So now it is time for a electic fuel pump. Please don't give me a lecture about connecting it so it runs with the key on. There is no option as 2 stroke engines don't have an oil pressure transmitter.
Thanks for any suggestions,
John
