Propane Enrichment Procedure: Notes

NOTE: All 1979 carburetors have the idle mixture screws sealed with a metal plug. This plug must be removed before any adjustments can be made.

To remove the mixture adjustment plug, proceed as follows:

Remove carburetor, then turn upsidedown and place on a holding fixture.
Place a punch between two locator marks on throttle body beneath mixture screw plug (manifold side) and break out throttle body to gain access to plug.
Use punch to drive out plug. If hardened plug shatters, remove loose pieces.
Reinstall carburetor on engine. Use a thin wall 3/16" deep socket to make mixture adjustments.
