The DLE 30 (mounted on a 73" CG Sukhoi) ran great this morning. I just had to open the L and HS needles a bit, but it spun the APC 18x10 beautifully. Maybe it was the carb cleaner ...

What's interesting to me is that hand-turning the crank shaft (with no prop bolted on and the engine and gas tank not mounted in the plan) did not pull fuel, but, as soon as I tried it while mounted on the plane, with a prop, it did (in 5 prop flips). Is it that the latter setup produces more torque \ pulse \ suction somehow?
