wow, thanks for that reply
terry sturchio I think this may help
the engine doesn't bog down at all, in fact - giving it just a little gas makes the car pretty much rocket off from the start, spinning tires and all. it's just when I open the carb up past half way, it flames out. the analogy of the faucet makes sense, so I will try that, richen the top end and tune the low end from there then the top end right? the pinch test wors out good, 2 seconds and then the car revs and dies. that's why I think it was the top end needle out of tune. RD logics said to leave the mid range needle pretty much alone, flush with the housing. I did switch fuels as recommended by the manual - using 20% to break in and now switched to 30% nitro, and I realize I will have to retune the motor each time I go out, but no matter what I do it seams that the motor just dies whenever I open the throttle past 50%
again thanks for the quick replies and help
