    Double check the float height. It should be level with the bowl. If not it can’t feed enough fuel to allow high speed running. That float controls the needle valve feeding fuel to the carb. If it’s off a bit…no adjusting the valves will help.

    Also check the high speed and low speed needles to seed if they are worn or grooved. If so they need replaced.

    Finally…these motors are touchy when adjusting the valves due to the carb configuration. So small increments and allow the motor to "adapt" after adjusting for 15 seconds or so.
