J50tlcde. New to me
Problem: will not run on both cylinders when under full acceleration after approx 10 seconds. If I keep squeezing the bulb making bulb rock hard it’ll run indefinitely under hard WFO. Let 10 seconds (or less) go by w/o squeezing and it’ll drop a cylinder. Squeeze to hard and get cylinder back.
Compression: 120 psi both cylinders . When I got it, among other things, I cleaned the carbs and replaced all new fuel lines. Engine starts easily cold and idles well for a while then it’ll surge faster then slower
The oil side of vro was disconnected and uses premix now.
to me, it sounds like I need to replaced the diaphragm on the fuel side of the vro pump as I don’t know it’s history. I have not put a vacuum gauge on the suction hose for the fuel pump but I will soon.
does the problem sound like a faulty fuel pump diaphragm to the experts ?
