47-55.1 Eliminate draft tube options

One step forward, two steps back.......

Engine runs on the new distributor, but I very quickly noticed no oil pressure. Checked all wiring to oil pressure sensor and gauge. Since all was well with wiring, I had a very bad feeling......

After considerable measurements and testing. The new distributor does not engage with the oil pump drive. It seems that while the measurement from the tip of the distributor shaft to the cam gear is correct and since the shaft has no collar on it preventing the shaft from dropping in, the shape of the shaft directly above the gear prevents the cam gear from fully seating, thus the oil pump drive never even touches. The old magneto shaft has a spacer above the cam gear that is smaller in circumference allowing the cam gear to fully seat and then permitting the oil shaft drive to be engaged.

I can use an old distributor shaft in my power drill and get both oil pressure and weeping along the length of the valve train, but with the distributor - nothing.
