I went back and read your posts on the other thread again @Mattax what curve should I be looking for? I have a spring set i can play with im gonna start over and check my timing again starting at 600 rpm and go up in 200-250 increments documenting it along the way. I will give you the numbers so you can make your neat chart graphs lol

If you take a compression test, you can get pretty close with the ignition cure the first time. It's just something you're gonna have to experiment with. Did you say you were running it 20 initial? I think you said you were going for 14 mechanical. What gear do you have? Maybe try it all in by 2500 and see. If you don't get spark knock, I'd call it good.
