What i'm saying is you will get close to max RPMS well before you get to the mechanical stop. softening the curve (lower numbers at the throttle points) will let you have a more fine control over the RPMs in the lower range. IE not like a light switch from nothing to everything all at once.

Like i said once you get it started it will all make sense....
OKay...I will be running a 18x8 break-in prop for the first gallon. So I'm setting up the needles for 1800rpms at idle. Then will I set the throttle curve to the max 9000rpm's that the engine is spec'ed at at the high end of the throttle curve? I'm sure I'll figure it out but just need to ask until I get to that point.
