Locate and loosen the lower locknut securing the auger control cable (shown in Figure 13). 3. To change the slack in the cable, turn the upper locknut slightly just until the slack between the spring and the exposed cable has been eliminated. 4. Tighten the lower locknut. 5. Test the units to make certain that the cable has been adjusted properly. WARNING Use extreme care when making adjustments that require engine to be running. Keep hands, feet, hair and loose clothing away from any moving parts. Testing the Auger Control Cable Start the snow thrower engine and pull back on auger control to operate auger. Release auger control and check to be sure auger stops turning. If auger continues to turn after auger control is released, cable is too tight and will have to be adjusted to make it longer. Cable must be slightly slack when auger control is released (away from handle). CARBURETOR ADJUSTMENT The carburetor is properly calibrated and preset at the factory for efficient cold weather operation. There are no adjusting screws on the carburetor. If it is apparent that the carburetor is not providing satisfactory fuel supply to engine, contact your nearest Authorized Tecumseh Service Outlet for service. 14 15 Troubleshooting & Service REPLACING THE DRIVE BELT 1.
