Where do the two ends of the return spring for the accelerator pedal attach on a troy built super bronco - disconnected the spring to address a belt issue and the spring went flying before I noted where it was attached - I have it attached at the moment so that the mower is useable but I have lost all speed - please

Hi,
You did not give much info, here is a picture I could come up with. The #54 spring attaches to the rod and the #17 cotter pin keeps located. The other end fits into of the #51 arm.
Peace,
Clarke
