I replaced my leaky Carter off my 53, 3600,216, with a Rodchester from CD, and I'm calling them tommarow about this Question. #1. The gasket in the center of the housing is DAMP, and #2 It runs with the choke in half open. I replaced 2 in line fuel filters ,NO teflon tape,(Liq. pipe dope), but it still will not run without tender foot work...Any ideas??? I tryed the adjustment screw a little at a time, no good, plus does anyone know where I can get the Rodchester rebuilt? This gas leak got me scraching my head, Thanks...Paul
