My KFIII rebuild has about 10 hrs. on it now with no real issues but I'd like to get it running smoother. It has the 912ul with the Ivo 72 ultralight prop. I've balanced the carbs with my Carbmate and they show dead on at 4100 rpm where it likes to cruise. It's not bad just not a smooth as some 912's I've flown. I'm wondering if I need to get the prop balanced ? Any ideas or suggestions welcome.
All and all it's a lot of fun, just a dirt simple little airplane that really performs.
Thanks,
EG
