Dealer has a couple blown 8010 that he will give me. These were warranty replacements. I am assuming these have piston and cyclinder damaged. When echo doesn't bother to have dealer send them in they know what is going on. I think it is dirt getting past filter. Looks like a cyclinder and piston kit would be around $180. Short block is an insane $400. Anybody rebuild? Doesn't look good for 8010.
