Having fun with timing

You said you have the mechanical at 16 degrees locked out. Do you mean that that's the most it will advanced or is it locked out?

At any rate, without any specs on the engine no one can say what you should have for a curve.

We need to use the same terms so we can understand what we are talking about.

Locked out means you have the mechanical advance inoperative and your total timing is whatever you set it at.

That would be 35 degrees or something. That is almost always a no no.

With that said, keep on learning. You are on the right track.
