This little spring mounts onto the throttle assembly that is bolted to the bell housing to return the gas pedal to the idle position.
The early style was used on throttle assemblies that had a removable lever on the end. This would be the lever that your rod hooks to from the carburetor. Early style comes with a pin to reattach the arm. U.S.A.
Three piece set needed to install the choke rod. The rubber grommet is for the bracket hanging from the fuel tank, leather washer, and steel cup washer.
The leather washer goes against the outside of the firewall and the steel cup shaped washer goes between the the leather washer and the choke rod spring.
The steel washer is the correct washer, not a floorboard washer. U.S.A.
