Book Excerpt: Allis-Chalmers Repair Manual D-10, D-12, D-14, D-15, D-17, 160, 170, 175 LP-GAS SYSTEM

The LP-Gas system available is designed and built by Ensign Carburetor Co. Like other LP-Gas systems, this system is designed to operate with the fuel tank no more than 80% filled. The Ensign model Mg 1 carburetor and model W regulator have three points of mixture adjustment, plus an idle stop screw.
ADJUSTMENTS 100. Starting Screw. Immediately after the engine is started, bring the throttle to the fully open position and with the choke in the fully closed position, rotate the starting screw(N- Fig. 61) until the highest engine speed is obtained. A slightly richer adjustment (counter-clockwise until speed drops slightly) may be desirable for a particular fuel or operating condition. Average adjustment is 1/4-turn open. Place controls in operating position by completely opening the choke. 101. Idle Stop Screw. Idle speed stop screw on the carburetor throttle should be adjusted to provide the correct low idle engine speed.

D-14 ..... 525-575 rpm D-15 ..... 550-575 rpm D-17 ..... 375-425 rpm
