Lots of good info here on fixing the evo .46. Just wanted to add something I found on my evo .46 after being on the verge of tossing it due to deadsticks, inconisistant needle settings, etc. I pulled the engine out of the plane and pulled the nipple that the fuel line goes to on the carburetor so I could make sure it was sealed. I found a good sized chip of metal in the hole. Once Ipulled out that chip and reset the needles to factory, it runs like a champ.
