Chain saws count?
Just came up from the garage to do some googling.

I put a new fuel line in my Stihl MS170 saw (large PIA). Anyway i finally got the fuel line snaked in under, behind and around (no room to use your fingers) and in the process the throttle pivot rod popped out of its mount. No problem snap the rod back in re assemble everything yank the cord a few times and she's running. Yay.....flip the switch to off.....saw keeps running. Had to pop the cover off and pull the plug wire off to kill it.

Looking at it i can see the wire that's supposed to ground it out ( it's slid into a groove on top of the throttle rod) but there's nothing near it to make contact with. humm...must have lost a part. Look on the work bench, floor, everywhere. Nada. Study the saw some more. Must be supposed to hit this metal tab under the throttle rod. Start saw, touch wire to tab, motor stops. Yup must have lost a part.... damn.

Do some googling-parts diagrams are no help- find a youtube video of a guy changing a carb on an MS170 freeze the video. You dumb a$$. That metal tab needs to be held up when you snap the throttle rod down so its ON TOP where the wire can make contact with it.
Facepalm.
