David, I paged thru my old note book, and found 2 potentials. This fellow was recommended to me by Greg Lucas, a few years ago. (Ted, 405-413-4972) Another re-builder is( Russel Romey, D&G Supply, Niles Michigan, 800-446-8160, 269-684-4440.) I dont think I ever talked to either, and the info is several years old, but worth a try. Susan Prall is a major Franklin supplier (903-626-5210) as is Southern Aero (336-687-9094) or (336-687-6158). I think that both of these suppliers send carbs out for overhaul, so they should have good recommendations. Let us know how it goes, and how much it costs. ______Grant.
