Ok, I know I have read about this somewhere, but
not sure where or what I read means, but I finally ran my engine up to full
power and was wondering what kind of numbers I should be seeing.
Even though I had some intermentant wire issue
(SUPRISE) in that as I got over about 4500 rpm the rpm would flash in the
hundreds and then go to zero. When I throttled back to below 4500
ish, the reading came back. This happened a few times.
However, later when I did it, the readings
were better and I was able to run the rpm up to about 5500 rpm at full
power on the Mistral Intake (so about 2534 rpm at the prop). It seem to
reach full rpm at about 3/4 (to 4/5) of full throttle and then mostly
stablized. Sounded smooth even though I am still running rich. It
seems to run much better with the mixture at about 9 oclock and bogs as I bring
it to the noon position. In auto tune it seems to be trying to
lean but kinda slow and if I try to keep it at the 12 oclock position it seems
too rich, so I think I will need to do some manual leaning and then go back
to the autotune. I am idleing pretty smoothly at about 1000
rpm.
Is this RPM range acceptable? Is this good;
bad? What should I expect? I was nervous to run it up like this, but I
just kept telling myself that I am not gonna be throwing a rod or blowing a jug
<g>. If you remember I do not have coolant temp reading right now,
so I closely monitored the oil temp and kept the run short, but I was curious as
to what I could run it up to. Thanks again.
All the best,
Chris
