Howdy Folks! New member, first time poster. My TB22 weed eater stopped working whilst in use. I checked the electrical assembly and it has spark. I placed carb cleaner in it no luck. I did notice when I started disassembling it that the rear cover assembly had melted flattened plastic in the vicinity of the piston rod. I'm guessing it was two circular edges that created a channel for the piston edge to ride in. I trimmed the damaged area out and sealed a crack that developed with JB Weld. I think the unit would not start due to a lack of compression in the cylinder section due to the crack. My question. Before I start it, does anyone know if the channels were required to keep the piston rod from warbling? Can not having the channel mess it
up?
up?
