sometimes the motor runs strong and other times while under load it starts bucking and jerking and even when its not under load. as if its not getting fuel. i replaced all fuel with fresh. plugs look new and dry. steady water stream..whats next?
Could be running lean and needs low speed jet opened up.-------Could be that throttle is opening too soon.-------Check the adjustment on the thin rod that goes to the back of the engine.--------Should be ~ 1/4" gap there at slowest idle position.
