That friend of mine from AutoZone and I took out spark plug #1, cranked until we felt strong compression on it and then I manually rotated the engine over with my torque wrench till it read '0'. Then we took a look at where I had installed the distributor (keeping in mind, I took photos, but not all were clear) it looked pretty darn close to the both of us.

Tell you what. I will get back to TDC with the timing mark at '0' and then take an overhead shot at where the rotor is this afternoon if that would be helpful.

:yesnod:

Next time you talk to your autozone buddy tell him to bring over a timing light with a dial on the back of it.

Next time I get him over here I will.
Here is ther photo that I was talking about with my #1 piston on the compression stroke, the timing mark at exactly Zero, and a shot of the rotor from above.

Checked, re-checked and then triple checked by the guy at the autozone. Thanks for positing this graphic up here, it really helped.

Thanks,
Shayne :cheers:

Ok thats not very good looking. The screw holes in the "normal" position would look like a square from that picture. I put it in the picture below. That to me looks like it is pointing at #2.

You know what, I rotated it to get the other bolts out so it was a lot more square looking like your picture before. Should have thought of that!

This is more like what we had it at:



Look better? Or do you think I might still be one 'notch' on the distributor gear too far advanced? (if that's possible to do. I've done so much reading I can't remember any more)

What did you rotate, the body of the distributor?

Yeah, the spark plug wires were making it difficult for me to get the cap of the distributor off, so I rotated it out of the way. It actually did make it quite a bit easier.

OK, I just had to be absolutely certain so I took spark plug 1 out and had my brother crank it over once to make sure I was at TDC. I guess I was on #6 with those previous pictures because with one revolution of the rotor, I got the compression I was looking for with cylindar 1.

So now I have manually rotated the engine of a few more degrees in its natural direction and put the timing mark right on zero.

Here are the two photos now, one close up and one for perspective.

You're in good shape now. Put the cap on and ID which tower the rotor points to with the greatest amount of distributor body adjustment.
Set #1 and follow the firing order around, you're good to go!! :cheers:
