I am going back to the old carburetor days, a brass swivel pin through the throttle butterfly. If you did not use the car for a while the throttle would start to seize, a mechanic told me that the brass pin would expand with age. I am wondering if the brass was absorbing oils etc and that was what caused the expansion? I had some expandable brass collars on the wheels of my old pier mount, one of which completley siezed in the aluminium leg so tight that I had to drill the steel pin out to remove the wheel.
