So I finally have the car running OK. When its running, the timing light shows it to be at about 40 - 50 degrees(??) BTDC (about 2" past the notches on the crank pulley). I think I may still be off by one notch, but its much better. I have to turn the service screw up to keep it idling at around 1,500, or it misfires alot.

My question is, how much of that can be made up by moving the wires back one position on the dizzy? Is it 60 degrees (6 wires, 360 total degrees). I must've put that oil pump in and out about 15 times before I got it this close, and I really don't want to do it again. I'm at 50 BTDC with the adjustment on the dizzy right in the middle. I'm thinking (if it is 60 degrees per spot on the coil) that moving back one, with plenty of adjustment in the dizzy still, should get me there.

Or, am I kidding myself, and I need to take the oil pump out again?

Actually one plug wire position would be 120 degrees of crankshaft rotation. The crankshaft makes two rotations for 1 distributor rotation. I havnt messed with my oil pump so I cant help you get that sorted out, but I'm sure some else here on the forum has.

If it were me, I'd pull the pump and do it right. It's not that big of a job, I've done it on my yellow car for this very reason. Half hour job, no more.

Like he ^^^^^ said:ermm:

One of the dead giveaways of a non Nissan aware mechanics work on an L series engine is an out of phase distributor drive and a re-programmed distributor cap to "correct" the situation:finger:

Yes, after you have got yourself adjusted to the situation, pull the pump and try again:tapemouth

Thanks, taking the pump back out this morning.

Like I said in the other thread, make sure the pointer and the mark on the pulley are 'spot on' before you set the dist drive shaft. You'll get it. I don't know how many times I removed and replaced the oil pump on my 510 (back in the day) until I got it right. Once you've been through that, I'll bet you'll never have a problem lining up an L series distributor again.
