[TR] TR3 Timing question

[jpaynepbr at cox.net]

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.
