Now that i have read some of the forums I'm confused.Problem is: I'm running the engine up (purchased used in a Comp-arf yak,appears to have very little time on it) and its not clearing out and I'm burning tons of fuel from earlier flights. I have only run a gallon and a half through at this point ,and I experience dead sticks if I idle down.On the ground the idle seems fine.Any comments or suggestions would be appreciated.I have had a da 100,and a 150 without any issue.
