Idle Mixture (Propane Method)
Fig. 1 Carburetor 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. 1, must be used to adjust idle mixture. Before proceeding,
make sure that propane cylinder is adequately filled to ensure correct propane flow.
