Got a «Choy bilt» troy bilt blower with the 2 year warrantee. used it maybe 6 times. engine failed after 13 months. Troy bilt says bring it to Home depot and Home depot says send it to troy built. Found the trouble myself, it was a retaining clip for one of the valves. Troy built wont sell me one, you must buy the whole engine for $ 113.00 and its still on warrantee.
