Ok, I know I have read about this = somewhere, but=20 not sure where or what I read means, but I finally ran my engine up to = full=20 power and was wondering what kind of numbers I should be = seeing.

Even though I had some intermentant = wire issue=20 (SUPRISE) in that as I got over about 4500 rpm the rpm would flash = in the=20 hundreds and then go to zero. When I throttled back to below = 4500=20 ish, the reading came back. This happened a few = times.

However, later when I did it, the = readings=20 were better and I was able to run the rpm up to about 5500 rpm at = full=20 power on the Mistral Intake (so about 2534 rpm at the prop). It = seem to=20 reach full rpm at about 3/4 (to 4/5) of full throttle and then mostly=20 stablized. Sounded smooth even though I am still running = rich. It=20 seems to run much better with the mixture at about 9 oclock and bogs as = I bring=20 it to the noon position. In auto tune it seems to be = trying to=20 lean but kinda slow and if I try to keep it at the 12 oclock position it = seems=20 too rich, so I think I will need to do some manual leaning and then = go back=20 to the autotune. I am idleing pretty smoothly at about 1000=20 rpm.

Is this RPM range acceptable? Is = this good;=20 bad? What should I expect? I was nervous to run it up like = this, but I=20 just kept telling myself that I am not gonna be throwing a rod or = blowing a jug=20 <g>. If you remember I do not have coolant temp reading = right now,=20 so I closely monitored the oil temp and kept the run short, but I was = curious as=20 to what I could run it up to. Thanks again.
