I've got an ancient Troy-bilt 34020 mulching mower, engine 122702-3182-01. It wasn't running well, so I took it apart and found this spring floating around the carb area, not attached to anything. No amount of Googling has turned up any help on how or where to reattach it. I have learned that its current part # is 690354. Obviously(I think), one end hooks onto the top of the choke, but there's no place I can see to hook the other end! I can find it on various parts lists but I can't find it on any diagrams. I know I should just buy a new mower, but I've had this one since 1996! My then-boss actually gave it to me as a bonus. Any help would be very much appreciated!
