Pulled it, checked it, was on mark. Put it back in, still no dripping at drip tube. Checked my IP tag for #251, the Nov. 1982 production IP with the gearing mark in the wrong spot. Mine is in the correct spot.

What should I do? I'm getting no drips, nothing, no matter how far I swivel the pump. What I've thought about doing is bolting the pump on and rotating the engine a couple degrees to about 22 BTDC to see if I can get any drips.

Would chain elongation/stretch cause the timing to be advanced or retarded? How do you compensate for this when installing the injection pump? I don't think that's the issue, though, because before removal, the pump was timed to 25 and seemed fine.
