Every timing light I used in my youth had no dial on it. You set the timing with the light, and that was that. I bought a timing light a few years ago, though I've never used it, and it has the dial. Being that there's no numbers on the timing marks, I can only assume you mean setting the dial to 24, and reading the timing while the engine is running above 2500rpms? Forgive my ignorance, please. I just never used a timing light with the dial on it.,,,,BB

With a dial-timing light you either double or halve the number on back, and I can never remember which. As far as the $60 pulley, I think he's talking about Racing Beat's piece. I believe someone took measurements once and the stock pulley is almost exactly 360mm around, meaning that you could just measure 24 and 16 millimeters forward on the pulleyand set your timing to those marks.

Well hell, that sounds about as easy as it can possibly be? I am out of town right now, but once I get home I'm going to be fixing the distributor, and marking the pulley with the new measurements. I know how timing can affect a piston engine, as I have hit just the right setting a few times on cars in the past. The difference is usually night and day.,,,,BB

I just had a thought?? Is it possible that the pulley was put on wrong? I see non factory looking sealer on the front cover. A medium blue colored silicone. I've heard they're keyed, is it possible it got put on 90* off? I have no idea when all this work was done to it, but it's been quite a while!,,,,BB

I'm also going to try and mark the pulley today. The trailing is always 8 behind leading, right? So I would just measure 24mm ahead on the pulley for the leading, and then 8 back for trailing?,,,,BB

Or is it 24 ahead from leading, and 16 ahead from trailing? If I just had a picture of what a marked pulley should look like, it would clear up a lot of my questions.,,,,BB

Yeah, there's a good chance that the pulley is just on wrong. Any chance that you're hooking the timing light up to the wrong plug (trailing instead of leading)?

Well, bottom front plug is where I hooked it up. I just found out a friend of mine of 3-4 years used to build fast first gens BITD. I'm trying to lure him over to the house to help me out with it. Beer and food, etc hehe....BB

So if the yellow mark is at TDC, where should the arrow on the rotor be pointing? Right now it's pointing to the upper left, towards the passengers side headlight--roughly--,,,,BB

Take a look at how your distributor cap fits on. The arrow should be pointing to the L1 post.

That's what I figured. That's pretty far off, almost an exact 180*. Which, by my past experience means it will run, but not all that well. So, if I pull the distributor and change it, and it runs horribly or not at all, then the pulley was off, not the distributor.,,,,BB
