Yep, turn the star wheel until it almost disappears under the access hole. If that spring in there gets loose, then you went too far. If you adjust it right, it wont smoke but maybe a little fog if you mash the pedal. I've used a big screwdriver with vice grips on the top to break em loose too. According to part numbers for Crafsman, a 3/8" slotted will fit the best and tightest in the screw slot. That AFC housing has adjustment in it too, so if it goes too far forward you'll see it puke black. A good starting point is to eyeball the middle of the adjustment.
Besides, this way you'll have some time to play with it, and have time to gather parts.
