Re: Loseing Power

Is the bulb soft when the engine quits? If you have someone slowly pumpling the bulb will the engine keep running? If so, you need to replace the three check valves in your fuel pump as they are sticking. Older check valves with clear or amber colored poppets tend to swell from alcohol in the fuel. You can see it happening by pushing them with a tooth pic or similar tool.

The new check valves have black or grey colored poppets and they seem to get along with gasahol.
