Gentlemen:

I have just attempted running in my new 82A. I had some issues. I followed the instructions pretty well and decided to run two times of 5 minutes each at the break-in mixture of 2 1/2 turns out on the HS needle. I was initially concerned because after rotating the prop 3 times, the engine lost all compression. I tightened the glow plug, but same thing no compression. I went ahead and gave it a few flips with the start stick 3rd flip it fired, ran a bit rough and increased rpm. I held it between 3200 rpm and 3800 rpm for about 2 minutes. It was going up and down a lot, but the engines I've broken in before they did that too on the first tank. Plenty of smoke in the exhaust and some fuel shooting out of the carburator.

THats when all hell broke loose. The engine started increasing in rpms. Then the throttle lever completely came off and it went to something near full throttle. I just held the plane and was thinking about the best way to stop the engine when it died on its own. The engine was hot, but I could put my hand on it for a quick second without burning it. The problem with the throttle lever was that it melted. I can not understand this at all. I checked before hand and it was fine, tight, and turning smoothly I don't even know if I can use the throttle lever now It seemed to be held on with a glue of some type and a set screw.

Anyone have ideas on this?

Prop was APC 14X4 wide, no spinner. Fuel was Wildcat 2&4 stroke 15%nitro, 18%synthetic.
Ambient temperature was about 85 deg. F and I'm at 500 ASL, humidity 0, engine mounted on airframe.
