Howdy all

Could never get my 912ul to run for balancing with the crossover tube

removed. All I had to do is increase rpm Duh!

It always runs great full throttle but they were off by 5 tics of what ever

the gage sold by Lockwood uses for display. Now runs good and idles well.

I was pitched 5450 rpm before. Now wot is as low as 5000. Rarely higher than 5250 - 5300. Of course some of the variance is thermal related.

Here's the weired part If I pull up hard I can always get 5350.

Take off is mind blowing. In the air the last 1/4 throttle doesn't seem to change rpm. Well that may be true on TO but I don't have time to think about checking it.



Anyone got a clue? I surely don't. :
