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.

@@austinalley5094oem vs aftermarket has to do with metal quality and tolerances. That being said, I have saved plenty of oem cylinders with sandpaper and hones, saved pistons with brass wire wheels and always new rings.

@@austinalley5094but I have also rebuilt with aftermarket parts with years of run time
