If it aint broke, it aint mine!
I had a guy at church bring me two saws the other day. A MS290 and a 026AV. He said I could keep the 026 if I could get the 290 running. I told him I would see what I could do.... [emoji19]
It took me about 30 minutes to get the 290 running. It had a dirty carb. He got his saw back and was happy as could be. I gave him strict instructions to run it dry before he put it up next time and down the road we go.
A couple of days ago I got that 026 on the bench and started breaking it down. It had the worst piston I have ever seen. It took me about an hour to get the transfer out of the cylinder using my jack leg version of the "Mastermind" method. I did get back to a serviceable condition though. Hopefully I will get some time today or tomorrow to put it back together. I am thinking about opening the muffler a bit. I have to do a little research first though.
Here is a picture of the piston I removed. It had transfer to the intake as well as the exhaust. There is a couple spots where the aluminum has the rings buried in the ring groove. I know some of you guys have seen worse, but I am only a jackleg hobby mechanic and this is my worst yet. [emoji13]
