Trying to resolve a problem with my daughter's scale boat. We've been fighting the same problem at the last 2 races. At the pond tonight, she was just doing laps at half throttle and there was lots of smoke in the air which made me think it's rich. Then it dies after 4 laps with a blown plug. Tried it again...same thing. We're using 50% fuel in a CMB 67 with new bearings and using a CMB black belly 67/80 pipe at 11 3/4" (c/l engine to weld on pipe). We've also tried different fuels and the results are the same.
We tried a different engine and although it still seemed to 4 cycle, it didn't quit nor did it blow a plug. All I can come up with is that the first engine is leaning out but I can't find out where.
Anyone got some ideas???
