I purchased a Weedeater gas leaf blower a couple years ago. I used it a few times in the fall of 2003 and again in the fall of 2004, it had about 8 hours of running time. Would not start this fall, it was still under warranty. I took it to a service center, they said that it had a hole burned in the piston from using old gas with ethynol in it and that would not be covered under the warranty. I have a 1976 Lawnboy lawn mower with a 2 cycle engine that is still running and have used a lot of old gas in it. Sounds like a rip off to me. I wrote a letter to Weedeater but never received a response from them.
