ran this 57 10hp last weekend with a gravity feed to the carb just to see if it would run. ran it again on saturday after converting to fuel pump.....ran well in the tank. tonight, i was tinkering with a different project.....and i hear "POP", from the general direction of the motor. had a look, and the plug i used for the old pressure line blew off? it wasnt clamped, as were none of the fuel lines for the conversion.
is it normal for the crankcase to hold pressure for two days??? bad or good?? :confused: ( am hoping this is good.....motor starts first pull after sitting for week)
