Put it back on! How hard is that. Make sure you hook the chain on the sprocket first, rest the bar flat between the 2 nut studs. Make sure the screw notch for the adjustment fits in the slot on the cover when you put it on top of the bar. snug the 2 nut up tighten the screw till you have at least the chain almost showing light through the middle of the bar! Too tight the chain will bind up when it warms up.
