Check yer carb settings. 1=high, 2 1/4=low. Brian

Sounds like carb settings to me.

what they say.

the starting settings for a zenoah g260 are 1.5 turns out for the high, 1.25 for the low, if ya wanna run slightly rich low end to be safe make it 1.5 also, 2.5 turns out on the low end needle is way to rich it will start to four stroke the engine and cause alot of buildup in the exhaust and ontop of piston, once run in lean of again, i have a 488 on my g260 its the biggest carb you can run on a g260 with having fuel draw problems.
