HF rpm Confusion

You need more precision than that when making jets for sub 100cc engines, .01mm increments.

I would think Butt-Stock, a clone should be good for a reliable sub- 5000 rpm operation, as long as the governor is removed properly. I think anything above that gets dicey for reasons of valve float, con-rod and (?)flywheel integrity.


As they always say as a caveat... "Your results may vary."
