    Is there any after marker part number you can find for these? One of our workers straight gassed it and blew up the exhaust side of the piston and put some bad marks in the cylinder head it had 30psi compression before rebuild.

      Cant find any on amazon but put this part number into ebay: Stihl 1141-020-1206 it should give you good prices on used cylinders from eb@y. I would definitely see if you can sand out the damage though. I save a lot of cylindrs that way.

    What’s the stuff called you are putting in the Cylinder for lubing it up. And the gasket stuff called for putting the block back on the saw body called . Actually in the process of doing this . And will go with that piston you installed. Very good information on the video thank you!!

      I used2 cycle oil for lube, and 1184 sealer for the gas resistant sealer

      Right on . Another question. My cylinder has slight scratches on the exhaust side . The sthil dealer recommended a new cylinder. Now price wise that’s up words of 275-330$ a new saw makes sense at that point . Do I put in a cheaper piston and put it together and see if it runs like crap . Kinda a toss up here on either a full rebuild or new piston . And what’s the difference between an oem piston and a regular one. Thanks.
