What I’m leaning on, Steve, may be the pressed on gear/shaft connection on the oil pump intermediate shaft. I’m going to fire it up this morning with new plugs, timing reset, and see if it eventually does the stumble and fumble thing again. If it does, I’ll reposition the engine to 10 BTDC and check the position of the rotor to the #1 cap position. If it’s off, I’ll pull the shaft and see if the gear is slipping resulting in the timing wandering. Stay tuned.....
Cheers Dave

I have seen the woodruff keys sheer off on a cam/crank. Could have been a soft one and the cam sprocket is no longer fixed in time to the camshaft. The typical 50 cent part sabotaging a big dollar project.
