Well I finally got it in and installed it. The tech's at DA didn't find anything wrong with it but my friends told me to go back to Penzoil 32:1 per gallon and that fixed the overheating issue. They said to not use Amsoil 100:1 for a long long long time. I also adjusted the needle like this: Low Speed Needle on 1 1/4 open and High Speed to 2 1/4 open and she ran just fine after that. I'm not sure if DA ran it long enough but when I received it I mounted the engine on my Reactor 50cc and bench ran it and it died and this is using a 6.0v ignition battery 1500mah Nicd with plenty of juice under load.

Got my maiden flight in about a week ago and she ran perfect and idled just right.
