A few years back I had a blower seize up on me. Took it to my dealer and they said its done for it, because I ran straight gas in it. I got it back after they couldn't't fix the machine and they switched fuel in it. The dealer is a big one but they are friendly and helpful, told me they would make me a deal on a new blower. I did and bought a backpack blower haha what a scam. Boy I was dumb back then I should have fought it, cuz the unit was somewhat new and still under warranty. I learned my lesson that day. Always speak up if you know something ain't right.
