[TR] TR3 Timing question

[Andrew Uprichard]

I think Randall's point was, you could have installed the pulley wrong:  the hole should be opposite the slot for the woodruff key.

Could you have gotten the distributor drive one tooth out where it engages the cam?  If   that is the case, it is fairly simple to correct - or you can leave it as it, just bearing in mind the timing will always look 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.
