Reply to "igintion timing for high comp engine based on roller"

Hi Matthias - at 800 RPM, you should not have any mechanical advance yet. So you should block off vacuum to the distributor, but you should measure it at the carburetor.

I believe your mechanical advance should be “all in” at about 2800 RPM. The ignition advance should smoothly increase as you increase the throttle above idle.

Good luck - keep us updated!
