I got engine running, 84psi in all cylinders, I put it in gear runs great right up to 1800-2000 rpm. If I try to go faster it will bogg and stall (as if its starving for fuel). Some one else before me bypassed the vro system, put a electric fuel pump on it and pre mix fuel. Pump is delivering 4-7lbs. Is that enough? Should I rebuild the vro and eliminate the electric pump?
