I just purchased one after being a little skeptical, but I figured i'd give it a shot. Can anyone offer any tips on tuning? I ran one tank through it on the ground, then four tanks in the air, all with the needle set rich, like the instructions said. After the final flight, I tried tuning it to get it to run a little better. No matter what I did, I couldn't get it to run right. It seems like it loads up, and runs really rich. If I dial the needle in a few clicks, it dies. The idle needle doesn't seem to change anything. Thanks guys and girls.
