I mounted the engine to a 2x4 and held that down to my flight box with rubber bands and completely retuned the engine from all the advice from this thread and some others. I was running way to rich on the highspeed needle and leaned out the low end a tiny bit. It's now running faster than it ever has before. Thanks for all of the advice. Hopefully the weather holds up tomorrow [8D]

One thing I noticed though is that it's getting extreeeeeeemely hot, and very fast. I probably only had it running on full throttle for 30 seconds but I would easily have burned myself if I touched any part of the engine. Is this anything to worry about? I don't know how hot these engines are supposed to be running.
