This historic book may have numerous typos and missing text. Purchasers can usually download a free scanned copy of the original book (without typos) from the publisher. Not indexed. Not illustrated. 1922 edition. Excerpt: ...back through carburetor takes place after engine starts, close the choker valve partway for an instant, to allow more fuel to be taken in. Never hold the choker valve for more than an instant; otherwise engine will become "flooded." After the engine has warmed up and explosions are regular and every cylinder is firing, open the throttle control wide and the speed should be controlled by the governor. It will take several minutes for motor and manifold to warm up, so do not do any adjusting if motor does not work correctly at once. When motor has become throughly warmed up and has been running under load for a few minutes the kerosene may be turned on by tuming fuel valve pointer toward position marked "Ker." After the engine has become throughly warmed up on kerosene and is operating on a load turn the handle of manifold damper to the cold air position. When using kerosene it is important that the motor be kept at a comparatively high tenperature at all times. (See page 25 for instructions on kerosene). If trouble is experienced in starting the engine read instructions on pages 33 and 34. The Clutch Lever The right hand control lever operates the clutch, and is used when starting and stopping tractor and in operating on belt work. It is also used to operate the pulley brake. When this lever is in neutral position the clutch is disengaged. Pulling back on the lever throws the clutch "in"; pushing the clutch lever to its forward position applys the pulley brake. Always disengage clutch and stop tractor before shifting gears. Use judgment in operating the clutch. Do not throw it in with a jerk when operating as this causes an excessive strain on the transmission and motor parts. Apply the clutch more
