This is the handle for a generic Briggs & Stratton throttle control that you can purchase at most hardware stores. Even though it is easy to go to Ace Hardware and buy another one, and even though the replacement is only about $10, the reason I did this is that they break pretty easily, and it gets to be a pain to keep buying them.

Also, I don't need the cable that comes with it (and also the part that holds this throttle lever), and hate to throw out a perfectly good cable and holder.

I created this by photographing the original part, after gluing it back together, and then tracing the key elements in Fusion 360 after first importing my photograph as a canvas and then calibrating the part by measuring a key dimension on the real part, and transferring that dimension to the photograph.

The part fits and works perfectly, although you may need to clean out and "true up" the holes that fit on the holder pegs, and the hole through which the throttle cable snakes. I just mounted the appropriate-sized drill bit in my drill and ran it through these holes.

You have to use supports. Other settings are non-critical.
