I got my DLE from Ralph. Mounted the engine in a plane and so far ran less than a half a gallon through it...about 4 cycles. Adjusted it, let it idle, picked up my plane and pointed it downward...engine stopped. I'm not an engine expert, but have experience with 3 new gas engines and 2 used.

Unfortunately the weather's been crappy here in Chicago and it doesn't look like I will be able to do anymore testing til spring. Following this thread for a solution.
