Have a question for you experts out there-
If I understand it correctly, engine will "self-time" themselves with RPM
due to different heats of the glow plug, i.e. high RPM=high heat plug element
lighting off the meth sooner= advanced timimg, and low RPM=lower heat "retarding"
the light off. Now connect a glow driver like some pattern guys have...always on.
Does that provide better hi end or low end performance or is it just a "belt and braces" thing
more for preventing flameouts during manuevers??
