RE: DF advice
Another way to set the low end is to close the idle screw all the way in ( with the throttle closed all the way and the speed needle a few turns out ), now put a piece of fuel tubing in in fuel port and blow air through it then turn the screw out 'till you can feel and hear air coming through, this should put you very closed to the low end setting, now go back run and adjust the speed needle.
