my problem is low idle when engine is warmed up, and stalls when i try to shif into gear. whenever i do get it into gear and accelerate lightly it misfires badly up to appx. 2000 rpms. but if you nail it theres no misfire.i have installed new plugs, and cleaned the 02 sensor. The fuel is new . The engine is a 225 v max yamaha 0x66. Any feedback is welcomed.
