LPG CARBURETOR ADJUSTMENT
Idle Mixture
Turning the idle air screw in will make the fuel mixture richer.
Turing the idle air screw out will make the fuel mixture leaner.
The idle air fuel mixture is best adjusted only with a engine CO
exhaust analyzer and the mixture should be adjusted to 0.30 to 0.70
percent carbon monoxide.
