I advanced the cam timing one tooth and that puts the cam's mark just on the driver's side of the pointer that's on that #1 cam tower. Engine started, but basically did the same thing.

The check of the ignition timing "looks" like it's really retarded. If I look at the distributor cam lobes, the heel of the points is midway between 2 lobes and doesn't come up on a lobe until something like 20* after TDC. But, at TDC, to just look at where the rotor is pointing, it's pretty much right there at that mark on the distributor body for #1.

Since the distributor is driven off the front of the gear that drives the injection pump, the only thing I can think is that the chain jumped a tooth which is making both the distributor and the fuel injection pump about 20* retarded.

Guess I'll be tearing into it in the morning. Son of a @#!%& !!!
