Carburetor Spring Retainer
This is it
The spring retainer is simply a U-shaped
piece of sheet metal cut and formed to
hold the compressed spring in position.
Using it

Once the carburetor spring is
compressed, slide the spring retainer
over the assembly.

Insert the extended throttle cable into the
carburetor slide passing through the
spring clip opening and the hole at the
bottom of the carburetor's slide.

Position the "bulb" at the end of the
throttle cable into its seat.  Orient the
plastic retainer with the carburetor slide
grooves and gently release the spring

Wallah!!!  Assembly completed!  Install
the assembly into the carburetor body,
secure the screws (be sure the cap is
oriented properly) and you're done.

airplane related tip, send it to me and I will post it on this Air-Bike
