Does anyone know if there are supposed to be 3 adjustment screws on a XL2 automatic? (a low,high, and idle) My carb seems to only have 2- one is the idle , I'm not sure which one the other is. There is another hole close to the one screw. I thought maybe the other adj. screw went there, the but got broken off somehow.

I have an original XL2 owners manual from1976 and it only tells how to adjust two screws. No mention is made of a third screw.

MANY CARBS ARE MADE WITH A NON ADJUSTABLE HIGH END SCREW.THE SCREW THAT IS THERE SHOULD ADJUST BOTTOM END THIS WILL HOWEVER HAVE SOME EFFECT ON HIGH END.
