Re: Missing at 3500 RPM and Above
You need to figure out if it's fuel or igntiont. It could be starving for fuel if the tank outlet was clogged. My dad's '32 roadster would run at a low rpm but run out of gas at higher rpm. I found it by mounting a 5-gallon tank of gas on the floor and going for a ride. The problem went away.
The electric fuel pump should me mounted as close to the gas tank as possible and the fuel filter there also, between the electric pump and the tank. I only use the electric pump to prime the system, then I run it on the mechanical pump. There are two kinds of electric pumps. One is closed when the power is off and one is open. You want the one that stays open so the mechanical pump can draw fuel through it.
