Default RE: GMS Engine Tuning Problem

Some of the GMS engines take longer to break in than others. Seen one that would die at full throttle for some time but eventually it went away with a little patience and more time on the motor. Mine runs on 5% nitro and it has the 'tuned' muffler, loves to run on either a bolly 11.5 x 6 or and apc 12x4. The only tuning problem that I have had with mine was using a MA10x6 after it had broken in, the thing just revved it's head off and could not get any decent sort of carb setting from it, many hours of frustration latter we tossed the MA and put the bolly on and not a problem since.
