Hi John,I found the problem:when I was barking in the engine it ran out of fuel at full rich about 3 1/2 turns out,on the needle valve, so when I refueled to taxi the fuel just filled the carb.I readjusted the needle valve to about 2 turns and that did the trick and now the engine purrs.I will test fly it on sat.I did some taxi test and the plane tracks good but I almost wore out the robert tries do you know of a good set of tries that look scale they are 4"
thanks Fred
