Adjustments located on the carburetor are main fuel (load) adjustment, start- ing fuel adjustment and the throttle idle stop screw. The idle mixture ad- justing screw is located on top side of regulator. The adjustments are pre-set at the factory and normally do not need re- adjustment; however, if adjustments have been disturbed, or any of the components serviced, readjust system as follows: Loosen lock nuts on start- ing fuel adjustment and main fuel ad- justment on carburetor. Turn both of these adjustment screws and the idle mixture adjusting screw on the regu- lator all the way in; then make the following initial adjustments. Starting adjustment screw IVA turns open. Main fuel adjustment screw IVz turns open. Idle mixture adjustment screw (on regulator) l^t turns open. Start en- gine and bring to operating tempera- ture, then place throttle control lever in low idle position. Adjust throttle stop screw to obtain an engine low idle speed of approximately 425 rpm, then turn the idle mixture needle on the regulator in or out as required to obtain the highest and smoothest en- gine operation. Readjust throttle stop screw, if necessary. Place hand throt- tle in the high idle position and turn the main fuel (load) adjustment screw in or out as required until the smooth- est engine (deration is obtained.
