Oliver 77 Pulling Engine Build

camplandfarms · Jul 2, 2017

I'm just finishing up an Oliver 77 engine rebuild, to do some pulling with, started with stock 216ci Super 77 gas engine, installed (shaved) 1550 head, manifold and exhaust. Engine started and ran great prior work, now am have great difficult getting the engine to start and run. There is spark and engine does start, spits and sputters and then quits. It almost seams the motor isn't getting enough fuel, I drained the tank and cleaned the sediment bowl, am running 93 Octane gas. I'm just using the stock carb for now planning on purchasing a 1550 carb. Would it be the carb that is causing the issues, I would have thought that carb would at least get the motor running at idle.............any suggestions?

How's your fuel flow? Pull the plug on carb and make sure you get steady flow.

I pulled the fuel line at the carb and steady stream of fuel coming to the carb, haven't checked at the actual carb as yet. Maybe I should consider installing an electric fuel pump, although again I don't understand why it worked fine without prior to the build.

Is the distributor drive in right and firing order correct. Need to see where rotor is pointing on tdc number 1.

Just a thought, maybe the manifold is warped and not sealing good.

checked and re-checked the timing, made a small adjustment, however yes have the rotor pointing at #1 at TDC

well I'm being to wonder, it's a brand new Intake manifold from Korves, however I suppose anything is possible. I may end up taking the manifolds off again off and checking it. You wouldn't happen to know if I'm suppose to torque down those nuts down that hold the exhaust and intake manifold onto the block?

Yes and make sure the 4 cap screws holding the intake and exhaust are loose enough to give. Start in the middle and work out 35 foot pounds should be fine with out looking it up. I also send you an e-mail. Did you receive it? J.

You do not need a fuel pump.

Valve train issue? Did you double check valve adjustment? Where different push rods required with shaved head?
