After filling it with gas and oil the unit would not start. After leaving it sit for a few hours the unit would start for about one to two seconds and die. I had to work the fuel flow switch for a few minutes before it ran steady. I tested it a few times and it seemed to no longer be fuel starved and ran steady. On my last try, in my attempt to get the hang if the unit, the ignition switch failed. I will contact the warranty 800 number to take it in. I like the unit itself, it is as promised, seems to run quiet enough.
