Flywheel timing mark wrong on HUP

[Phil Waterman]

Hi Malcolm

I will assume that the engine was running fine, and nothing had been disassembled prior to using the timing light. Now possible cause:

1. Firing order and spark plug leads, the engine really doesn't care which hole on the distributor cap, as long as they are in the correct order.

2. The gear on the end of the distributor shaft has shifted. I had this happen on the road in my C60S pin broke then jammed at a different point. Hole in the shaft was elongated from wear, have found several distributor that had loose gears.

3. Which timing hole are you looking through? Assume the one on top of the starter and not the one one manifold side of the engine.

Just some thoughts, because the timing mark is so hard to see, I've added timing mark to pressure plate so I can time the engine through inspection plate. When I have engine apart I mark the drive shaft with the three TDC with white paint saves time adjusting the values.

Cheers Phil
