Re: Distributor install question
A couple of things:
- Just because the timing pointer is at TDC, it doesn't mean #1 cyl is in the firing positon. A 4 stroke motor hits TDC twice through a cycle - once firing and once exhausting. Make sure #1 is @ TDC firing (both valves closed)
- With dist in your hand, install the rotor and look at where it is pointing as compared to the oil pump drive . On every GM dist I have looked at, the oil pump drive and the rotor were lined up. Unfortunately, on every MSD dist I have looked at, they're not. So just eyeball it, and if the oil pump drive is at 12:00 for example, and the rotor is pointing @ 3:00, shine a light down the hole and line up the slot in the pump shaft with that relationship in mind. I hope that made sense!
