outside into the air. Exhaust gases are toxic. Opening doors and windows may not provide adequate ventilation.

The carburetor is adjusted at the factory. Do not make adjustments unless absolutely necessary. Fac- tory settings are correct for normal operating conditions. I f adjustments are necessary, proceed as follows:

The

Start the engine and allow it to warm up at 3000 RPM. Turn needle valve in until engine misses (lean mixture) then turn it out past smooth operating point until engine runs unevenly (rich mixture).

Turn needle valve to the mid-point between rich and lean so engine runs smoothly. Hold throttle at idle position and set idle speed, adjusting screw until engine idle speed is 1800 RPM. Hold throttle at idle position and turn idle valve in (lean) and out (rich) until engine idles smoothly. If necessary, correct idle speed. Release the throttle -engine should accelerate without hesitation or sputtering. If engine does not accelerate properly, the car- buretor should be readjusted, usually to a slightly richer mixture of needle valve.

Recommended Fuel

This engine is designed to operate on leaded gasoline with a 93 minimum octane rating or on unleaded or low lead gasoline with a 91 minimum octane rating (Research Method).

use of unleaded gasoline will lengthen spark plug and valve life, maintain engine performance longer, and reduce rust and corrosion of enginewhile

stored.

CAUTION! Handle gasoline with care, as it is highly flammable. A. Use approved

gasoline container. B. Never remove the fuel tank cap or fill tank when the engine is

running, is hot, or indoors. Also, do not smoke when working around flammable fuel. Wipe up spilled gasoline. C. Replace fuel tank cap securely.

battery is located under the hood and in back of the fuel tank.

A charging circuit built into the engine provides a charging circuit output from 2 amperes at 2400 APM to 3 amperes at 3600 APM and uses lessthan

.2 horsepower.

Check the battery level at least once a month.

Keeping the battery fully charged not only adds to

its life but makes it available for instant use whenneede
