I made/installed an "adjust on the fly" fuel screw handle shown on motoman393's web site today. Problem is, somehow the threads on my fuel screw got messed up and now it won't thread back in. Does anyone know of an easy way to fix the threads on these? I talked to a guy I know who runs a machine shop, and he said that it was imperial fine threads and good luck finding a die. A new screw is $30, but that may be my only option. Anyone have any ideas?
