Chainsaw Repair

I've got a clam shell Craftsman/Poulan of around 46 cc that was given to me .It also wallered out all the mount bolts .How I found that out is because of the way that one was made when the engine rocked up in a power cut it would disengage from the oil pump. No bar oil ,smoked the bar a tad bit .Also screwed up the start pulley too I might add which is why I got the thing in the first place .My wifes cousin got tired of replacing start pulleys after three of same in about two weeks .

The fix was drilling out the mount holes to 1/4" and re tapping the holes to 1/4" 20 and installing grade 8 socket head screws .
