Hello all. This is one of the older M18C (SN 22229) with the "free-floating" float. The float has no tab connected to it. You can see the illustration for clarity.

Is there a procedure for setting the float level (height?) If so....can you tell me what the spec is?

Thanks so much. My engine runs very well at mid to wide-open but seems to be rich (4-stroking) at above idle to mid. Advance the throttle past that and it clears and runs great.

Thank You.
