I have an update on my engine idle problem.

I contacted VVRC, and explaned my problem, and they gave me permission to remove the carb for a better look without voiding the warranty. I proceeded to remove the engine from the plane, and once removed, I could see what was causing the problem. I had installed a ball link on my engine throttle arm and the threaded 2-56 shaft of the ball link extended below the nut enough to just barely make contact with the rear of the engine to prevent the throttle arm from closing all the way. I filed about 1/64" off end of threaded shaft to get the clearance I needed. I reinstalled my engine and ran it yesterday, and the high idle problem is gone. Now I just have to get the engine tuned properly.
