Hey Mark, Just got done trying your method to tune the DA and I have a bit of a problem. after setting for peak RPMs and beginning to adjust the LE needle to stop four cycling until idle, I begin to open up the LE again whenever the engine starts to bog down when going to full throttle. My problem is that I can't seem to get rid of the 4-cycling without going too lean on the engine. as I have it right now it takes a bit of time to start (which makes sense) and I have to warm it up for about a minute before increasing the trhottle, otherwise the engine stops. It still 4-cycles at about 25% throttle. is it still too lean? I richened it up since I had a deadstick when going from idle to full to pull out of a hover (doing it high to test the needles and such).

Thanks a ton,
Izzy
