Don't feel bad we all been there, I bought a new weedwacker a few years ago after old one died and the 2nd time using it wouldn't start after about a half hour trying to start it iam soaking wet from sweat pulled the plug out twice using a torch to dry the flooded cylinder out of fuel tried starting still nothing then realized the old one had a kill button this new one had a on off switch that I forgot about, switched to on and fired right up, I called myself a bunch of cuss words along with dumb S.O.B.
