There have been several factories in china that have made the motors used on buffalo generators, a couple of these are Lifan and J.D. as in Jiangdong.All of these motors are very similar to honda motors.The 6.5,13,and 15 h.p. motors are real brutes and hold up very well.

Idle speed jet or passage and/or high speed jet/passage is clogged. Remove the carb and inspect and clean thoroughly, then re-install. Set idle and high spped screws approx 1 turn and tune to run smooth from there.
