TBW on DW's Freewheeler suddenly would not return to idle. I moved the switch housing and it worked for a day but then it it began misbehaving again. Took it all apart and discovered that the housing and rubber grip were sticky. Careful examination of the goo led us to believe it was bug guts. SPLAT! Cleaned the goo and the sticky and the throttle works fine.

 

Thanks for sharing, this information could come in handy sometime.

 

Bug guts must have bee the inspiration for super glue. LOL

 

Good find. That sticky bug guts jammed up the throttle tube. A good clean is all it needed. Simple fix for a weird problem.
