Gasoline Engine Instructions
Second.Place the spark lever No.403, (Fig. 13) in the starting position and turn the flywheels to the right until the igniter trips, then stop.
Third. Prime the cylinder by filling the priming cup four times with gasoline and let it run into the cylinder, then close the cup. If the engine has been running and is still hot only fill the cup once.
Fourth. Open needle valve on the mixer two full turns to the left, close the air damper and then turn the flywheel to the right one-half turn or until the crank is on the outer dead center.
Fifth. Take hold of a spoke in the flywheel at the top with your right hand and put your right foot on a spoke at side nearest the magneto, pull with your hand and push with your foot, giving the flywheel a quick turn back toward the cylinder, at the same time trip the magneto with trip wire or with a screwdriver by placing it between the armature No. 100, as shown on page 37, and the magneto body and pushing downward which should start the engine.
Sixth. As soon as the engine starts open the air damper on the mixer, shift the spark lever No.403, to the running position and close the fuel valve slowly until the point is reached where the engine runs with the least number of explosions, as explained above.
HOW TO ADJUST THE GASOLINE FUEL VALVE
The mixing valve (Figure 5) is of the suction feed type, gasoline being drawn from the tank in the base by the Suction of the piston. The air and gasoline are mixed in this valve to form the explosive gas.
When you start the engine. open the fuel valve, close the air damper and turn the flywheel to the right; this draws a supply of gasoline from the tank and primes the valve. It is a common mistake to flood the cylinder in starting engine. Open fuel valve 2 turns on 1 3/4 and 2½ H. P. engine and from one to two turns on the larger sizes. In cold weather use more fuel. After the engine is running, open the air damper and close the fuel valve slowly until the point is reached where the engine runs with the least number of explosions and without black smoke appearing at the exhaust, or a popping sound at the mixer, the latter being caused by an insufficient supply of fuel, and smoke at the exhaust by too much fuel.
If it is ever necessary to take the mixing valve and feed pipe off the engine, be very careful not to lose the valve Out of the check valve, because if this valve is not in place your engine will not get any gasoline. To drain gasoline from tank remove drain plug. (See Figure 5.)
