Air/Fuel Mixture: Adjustments
Idle Mixture (Propane Method)

Fig. 10 Typical propane enrichment tool

    This procedure should only be used after normal diagnosis has revealed no other faults, or if carburetor has been overhauled. Idle mixture adjustment
requires artificial propane enrichment. A propane enrichment tool, C-4464 or equivalent, Fig. 10, must be used to adjust idle mixture. Before
proceeding, make sure that propane cylinder is adequately filled to insure correct propane flow.
