I have searched the forum and found remarkably little information on this topic.
I have the Mattituck test cell data that shows a 26 degree advance, however the engine data plate says 25 degrees.
I checked the actual timing and it was a schoch over 26 as the run in sheet indicated.
So why am I looking at it?
When I use my G3i electronic ignition during high manifold pressure it makes a popping noise from the exhaust. It sounds like the same popping that we all get during a descent, but occurs at a totally different point in operation.
I figured that a good starting point would be to set the timing at nameplate and go from there.
In my search for the "proper" setting, I have heard many people using a varied range of settings.
What is the reason for this?
