AS a matter of fact I have, RCIgn. Not with a degree wheel, but with timing marks scribed on the hub/crankcase for reference. Yes, the engine advances, and yes, sometimes it's dead nuts on "zero" reference at idle (1100 rpm) but come up a hair off that and it advances, and it does not always do it at the same point, nor always drop off the timing as the rpm comes down. I don't mind that it does this. . I'm not using that part of the power band to begin with, and it probably helps the motor stay running in the air during long low-throttle glides.

Personally, to me, the timing curve of the ignition is fine, and down at the bottom it's not worth worrying about. Heck, I would never have checked it if Keith had not mentioned it to me in the first place. But, it seems a difficulty was perceived at idle rpm, where the engine seemed to be "hitting" too hard, and causing the characteristic "BME SHAKE" that a lot of people find bothersome. IF Keith, Ed and others are taking steps to smooth this out, GREAT!!. . it can only improve the end product.

Now, if you'll excuse me, I have to go work with some logarithms and algorithms. . . .
