Chainsaw Repair

When I got the saw I didn't break it in    Seems you have to do that with these big saws and I just set to bucking up a large dead Fir and never let the saw cool down or rest.  Just kept getting into the wood, burying the bar and cutting round after round....expensive lesson to learn but I got the parts to rebuild for $181 on Amazon which seemed better than the $650 repair quote I had 

OK as for the carb -- leave the bolts in and pull it with the cyl head?  I'm guessing that I'll need to remove the linkage or at least the throttle cable and hoses?
