All factory pulleys will have a TDC mark. The question is are you on #1 or #3. To find out remove both valve covers. Put a wrench on the alternator/generator nut and rotate the engine until the TDC mark is in line with the case seam. Then have someone rock the engine back and forth as you observe the valves on #3. If they move then you are on overlap on TDC for #1. If the valves for #1 move then you are on TDC for #3.

When you think #1 is at TDC, slide over and look at the valves for #3. When your buddy up top is moving the crankshaft 2" on each side of TDC with a wrench, those valves will be tapping "like fingers on a table" if you are at TDC for #1.

If they are tapping at #1 when you do that, you are at TDC for #3.

Try replacing points and re-timing it.

I assume you are getting no reading on the dwell meter?
