Thanks Bob,
Iâ??ll check the mark against other cylinders, never thought if that.   I timed 
like you did, just listening till it felt right and no ping.

I was having similar issues and then discovered that when the hole in the 
pulley was at the pointer, cylinder 2 was at top dead center. So now if I'm 
using a timing light, I hook it up to cylinder 2. But mostly I just use static 
timing. When I was a kid working in garages, we would rotate the distributor 
until we got a smooth idle and quick response to the accelerator.

It's more likely that the distributor drive gear is off by a tooth or two than 
the pulley being put on wrong.  

There is only 1 way to get the pulley on and no opportunity to mess it up.  The 
drive gear has a 10 or more teeth on it, and therefore 10 or more opportunities 
to get it wrong.

Thanks Randall,
40° was just a guess, the mark is about at the 2:00 position.  I am using the 
hole in the pulley as the TDC mark, there is also a file mark there.  

I turned the dizzy clockwise until it started to stumble, then brought it back 
to the best smooth RPM position.   First road test was great, compression at 
175 across 4.  Can I leave it there?  If not, what should I be looking for?

Sounds to me like your TDC marks are wrong.

If the issue is the front pulley being assembled wrong, it would be off by
60 degrees, and so you're still about 20 degrees fast.  That is likely to be an 
issue.

40 late isn't going to work well either.
