It has to be ran at full throttle or 1/4 to 3/4 depending on what jet you are checking and the motor has to be cut of and the clutch pulled in at the same time while still on the gas. then coast like that to a stop pull plug and check.

that doesnt sound like fun, havin a burning header half an inch from your hand

you can do all that, or you can simply putt around in 3rd or 4th gear and hold the throttle steady, and flip your choke on........if it runs better, your lean, if it runs worse, your jetting is either correct, or rich.
