Hello,
New member here looking for some help. Have '75/'76 235 that just shut off on me after running perfectly for an hour or so. Plenty of fuel. No warning. No unusual noises. Just like I pulled the fuel shut-off. Dragged it back to the shop to try to figure it out. It didn't seem like I was getting a lot of fuel from the transfer pump, so replaced the pump and filter. Have good flow from the tank. Primed the filter. Have good, clean flow from bleeder at filter using lever on transfer pump. Moved around to injection pump side. Open the bottom bleeder on the pump housing and, spinning the motor over, I have good flow at that bleeder. Moved up the the other bleeder, the one I guess on the governor housing and, absolutely nothing. Not a drop of fuel or a wheeze of air that I can tell. Tried it with fuel shut-off in and out, at WOT and at idle. Any idea what this is telling me? I took the cover off of the timing cover and the little inspection cover off of the pump to verify that the pump is turning and it is. I've looked at some you-tube stuff on this pump and I see there's a spring in the governor housing that controls throttle I assume. Is it possible that this spring broke? Whatever happened, happened suddenly and without warning. Thanks for any and all advice. Not a diesel guy to start with and am a little lost. Can't really afford to just pull the pump and spend $6-700 to have it built. Thanks.
