The mixing valve is of the suction type. The fuel is drawn from the tank to the cylinder by the suction of the piston. The air and gasoline are mixed in this valve to form an explosive gas. When kerosene is used the water is also mixed in the proper proportion, so the piston on the suction stroke will take in a mix ture that will burn clean and not leave any carbon deposit. The fuel enters the mixing valve through the fuel valve, the water through the water valve and the air through the air intake. The air damper should be wide open when using gasoline. When using kerosene, close the damper about two notches on the ratchet. By closing this damper you in crease the velocity of air coming through the air damper, which helps to break up the kerosene, forming a more explosive mixture.

HOW TO ADJUST THE FUEL VALVE.

The supply of fuel is regulated by the fuel valve. If you open the valve too far, black smoke will come from the exhaust. If you do not have it opened far enough, the engine will run irregularly and may explode out of the air inlet called back firing or there will be an unusual sucking sound at the air inlet, as though the engine were gasping for breath. Keep the fuel valve set so the engine runs regularly, does not back fire and there is no black smoke at the exhaust.

DENATURED ALCOHOL TO REMOVE CARBON.

Our method of mixing a little water with the kerosene and air allows the engine on the suction stroke to take in a mixture that will burn clean and not leave any carbon deposit.

If you watch the adjustment of the carburetor and are always sure to turn on the right amount of water when burning kerosene, you should not be troubled with carbon in the cylinder from the fuel you use.

If you feed too much kerosene or lubricating oil, the extra quantity of either is liable to result in a carbon deposit in the cylinder or on the igniter, but by using denatured alcohol you can easily and quickly remove this carbon without having to take the engine apart.

Fill the small tank on the side of the engine cylinder with denatured alcohol and run the engine until the tank is empty. Do this once every two or three months and you will have very little trouble from carbon. If you are running your engine constantly day after day, it might be well for you to do this once a month.

Denatured alcohol is not expensive; it can be purchased at any drug store, and for this, little expense once every two or three months you will be repaid many times over by the smoother running of your engine, no trouble from carbon and more power from the engine.
