Cliff, on my 73-4 Quad. jet there is a plastic style bushing that go,s in side of carb. where choke arm go,s thru. The arm basically rides on it taking up slack the way i see it. Mine is completely dryrotted and fell out. Don,t want the hassle of looking for a donor carb. then trying to sell it. Do you sell these plastic style bushings. May be hardned rubber with a undercut in the middle. Very hard to locate.
