I've a 914 Chris, initially I tuned it at 2500 but found it was rough at id
le & at full power. After reading reports & watching videos by Rotax engine
ers who advised balancing at 3500, I rebalanced my carbs at 3500. The engin
e became very smooth all RPM settings & still is 30 hours later!
Btw
I used a standard Analogue Gauge Balancing Kit.

I=99m going to stick to this version of the tread. Why are there two?
Anyway, I do my carb balance at 2500 but also check at 3500. Found that if
I make it perfect at 2500 I get smoother low rpm operation but if at 3500 a
little nicer at cruise. I=99ve been told to split the difference. No
t much difference between the two though. My electronic balancer is very se
nsitive.
Unfortunately sync will go out as I get to 1800 and just a little off at 40
00. Sometimes it is better, sometimes worse. But overall runs nice. Better
now after the idle mixture adjustment. Just being picky. I am convinced tha
t if a butterfly farts in front of the airplane the tuning changes :)
Just came back from a flight. Runs good.
Chris :D
