Looking back on the initial start-up of this engine, we had some trouble getting oil pressure. We put a priming shaft with a 1/2 HP drill motor in the distibutor hole and ran it wide open and got no oil pressure. We then started cranking the engine and running the drill motor we got oil up top. It seems we should have gotten a trickle with just the priming shaft and drill motor. I thought at the time something must be pretty tight.
