fix-n-fly,

Thank you very much for such informative feed back as well as the exploded view of the engine. I did see the ring that goes between engine and carb, and I don't recall I had that one, that could be the problem as well. I wanted to try TT and never heard a bad thing about it, but I guess it was my luck. I'm gonna take some other measures to run it, I'm gonna clean out the fuel tank, take the carb off and do few other things. As far as old fuel is concerned, my fuel is few months old, once I had old old fuel but may be a year maximum and it completely got discolored, whatever the pink color or dye it had it completely dissipated and ran all the fuel through the motors, not a problem, and this fuel is pretty good, but I'm gonna try out the new fuel. Merlin plugs seem to be working good, and I read and heard good thing about 'em as they have long heads as compared to O.S. plugs. Mostly engines require hot plugs, but I'm gonna try medium in it. I'd keep y'all posted.
