This is the second time this has happened to me on this saw. The first time my dad put straight gas in it. It looks similar and I used acid and sandpaper to clean the inside of the cylinder and just added a new piston. It wasn't perfect but it looked pretty good. I am wondering if this contributed to the new piston failing? Or could it be something else?
I'm using 2.6 mL of 2 stroke engine oil for 1 gallon of gas.
Anyone have thoughts on what caused this and if I should just try and polish down the cylinder again or if I should just replace the whole top end this time?
