SERVICE AND ADJUSTMENTS ENGINE TO ADJUST THROTTLE CONTROL CABLE (See Fig. 29) • Loosen cable clamp screw to allow cable to move. • Move throttle control lever on upper handle to "FAST' position. • Pull throttle cable out until engine bellcrank is back as far as it will go. • Hold cable in this position and tighten clamp screw securely. THROTTLE CABLE CLAMP SCREW TO ADJUST CARBURETOR The carburetor has a high speed jet and has been preset at the factory and adjustment should not be necessary. However, minor adjustments may be required to compensate for differences in fuel, temperature, altitude or load. If the carburetor does need adjustment, see engine manual. IMPORTANT: NEVER TAMPER WITH THE ENGINE GOVERNOR, WHICH IS FACTORY SET FOR PROPER ENGINE SPEED. OVERSPEEDING THE ENGINE ABOVE THE FACTORY HIGH SPEED SETTING CAN BE DANGEROUS. IF YOU THINK THE ENGINE-GOVERNED HIGH SPEED NEEDS ADJUSTING, CONTACT YOUR NEAREST AUTHORIZED SERVICE CENTER/ DEPARTMENT, WHICH HAS THE PROPER EQUIPMENT AND EXPERIENCE TO MAKE ANY NECESSARY ADJUSTMENTS.
