Chainsaw Repair

I have a 40 cc Poulan wild thing that was given to me because the cylinder and piston was scored.     It gave me the opportunity to see first hand how they are made.    Other than it has no Antivibe it seems to be made as well as some of the older small Poulans I have.
    There is a large group of people that buys these saws and really know nothing about chainsaws in general.    You will see things like clutch covers that have been cooked from running the saw with the chain brake engaged.  The bars are so plugged up that oil would never get to it for oiling.   Letting old gas sit in the saw and then trying to run the saw with bad gas.   Chains on backwards, and so dull you would do better with your butter knife.   Rakers not at the correct height.  Sprockets that are grooved badly and should have been replaced.   Bars that are uneven and have hugh burrs on the sides from leaning on it to get it to cut.    Large areas of excessive heat discoloration on the bars from lack of oil.   I could go on and on.    But I do not think it is as likely to find these types of examples on pro saws because of the people that use them.
