Oddly enough, I had a Pranger (foam with packing tape for adhesive and a pine spar..

) when working in England about three summers ago. It had an EVO 46, not the trainer version, but the .46 version. I believe their trainer is 40 size. Anyway, doen't matter. The .46 ran just fine over there, but after I brough it back here and put it on a Goldberg Wildstick 40, it ran like crap, would not stay running, all the same symptoms as I had with the 100. That really confused me because we really put it through the wringer in England, and it ran fine with plenty of power. That 100, when it ran, seemed that it would do fine, but it was a POS. It would deadstick shortly after leveling out after my initial takeoff-turn to downwind forcing a deadstick landing.
We played with that thing until we were blue in the face with no success. We were going to put a $90.00 OS carb on board, but I figured for what it cost me total (engine plus carb), I could almost buy an OS 1.20 AX which I did. The EVO 100 is still on consignment at the LHS. No one wants that POS and I can't blame them.
