PEH,

That's interesting to know. I kind of figured there would have to be some kind of advance mechanism, but if you limit the RPM, you may get by without one.

Here's a couple of followups: (1) Does anybody ever tune the initial advance till it "runs right"? That's how one would tune most gas engines (using a timing light, of course). For instance, if you set my M117 4.5 to book (5 deg ATDC), it runs like poo-poo.

(2) What happens if the diesel timing is too advanced. In gasoline engines, too much advance at speed knocks. Too much at idle and the car won't start (kickback).

Thanks for the info,

Sholin
