Chainsaw Repair

If that thing is hung by the piston you'll never be able to pull it off unless you have the arms of King Kong .

If it's hung tight above the exhaust port you could shake it the grease gun trick .Below the only thing I can think of  is get the cylinder up above the crankcase if possible then split the cases from around it which would be a chore to say the least .If all that could be done you might be able to shake it upwards with a dead blow hammer or it just might be a lost cause .If it's rust hung you might save it,lean run stuck the piston and likely the cylinder is toast.Then it's off to find a donor because they haven't made that thing in ages so parts are going to be like looking for a hens tooth .--restoring old saws is not for the weak at heart---

First thing I did when I got it home was fill the cylinder with some PB blaster. That is soaking in it now.
