I rescued a cheapo 2015 era craftman handheld 25cc 2 stroke blower from the trash and it had zero compression. It would not even move the needle.
I pulled the cylinder only to find the cylinder to be in MINT condition and to my surprize was indeed coated in some kind of cheap chrome plate.
The ring had completely carboned itself to the piston and i was able to free it up and clean everything spotless. The ring was mint after cleaning with steel wool, and the cylinder had no carbon buildup or scratches.
Upon reassembling it, I now have 40si or thereabouts and it does not start well, or idle well but it does run at WOT very good.
Why is the compression so low? Does the stuck ring need to break back in to the cylinder surface?
