HOW TO PUT ON THE CAM ROD SPRING

The cam rod spring holds the cam rod and roller against the cam on the cam gear. As this spring does a lot of work it may wear out; if it does, buy a new one. (See No.059 in list of repairs, page 28.) To put on a new spring, remove the cylinder head, slip the spring over the end of the cam rod and replace the cylinder head. If necessary to repack cylinder head, see page 18.

HOW TO TAKE OFF A FLYWHEEL OR PULLEY

To take off the flywheel, loosen the bolt and drive iron or wooden wedges into the slot, one on each side of the hub. This will loosen the flywheel so it can be removed. To take off the pulley on the 1¾ horse power engine loosen the set screw with a screwdriver and drive the pulley off.

If you have to drive the flywheel or pulley off the shaft, use a piece of hard wood against the hub of the wheel and do not drive too hard. A number of light blows will loosen the flywheel without danger of breaking.

To remove the friction clutch pulleys, see page 24.

When replacing flywheel, place wheel in proper position on shaft, tighten the bolts down securely and drive in key.

To replace the friction clutch pulleys, see page 24.

If you find it necessary to take the governor apart, first take off the governor pinion. To do this, hold the flywheels stationary, which locks the gears, then take a wrench, stand on the governor side of the engine and turn the governor balls to the right, as the pinion is put on with a right hand thread. The governor spindle screws into the governor pinion and is held in place by a small set screw in the governor pinion.

VALVES

The inlet valve "A", as shown in the illustration is opened by the suction of the piston. For the entire length of the suction stroke gas is being drawn into the cylinder; then when the piston starts to compress the gas this valve closes and is held shut by the valve lock "C", so that no gasoline is wasted.
