ordinarily stay in the position it had before the ignition was switched
off. At such times, therefore, the reading of the gauge is not a true
reading. A true reading is given only when the ignition is switched on.
As filling station rules forbid running the engine while the gasoline tank
is being filled,on such occasions the ignition should be switched off until
the engine stops and then switched
on again, and left on while the
tank is being filled.
Figure 3. The gasoline gauge is operated
electrically by current from the ignition
circuit.
Temperature Indicator
If the fuel supply should give out
on the road, so that the vacuum
tank on the dash becomes empty,
it will be necessary after refilling
the gasoline tank to prime the
vacuum tank. To do this, close
the throttle and hold the starter

The small gauge at the right of the clock (Fig. 4) is a thermometer for
indicating the temperature of the engine,
and takes the place of a temperature indicator
on the radiator. The bulb end of
the thermometer is inserted in the water
jacket at the rear end of the right-hand
cylinder head, and is connected by a small
tube to the dial on the instrument board.
The normal engine temperature after
the engine becomes warm is 160° to 190°.

Throttle Control
Figure 4. The temperature of the
water in the cylinders should range
from 160° to 190°.
The power and speed of the engine are controlled by opening and closing
a throttle valve in the carburetor. This throttle is operated both by a hand
lever and a foot pedal.
The foot pedal, or accelerator, is at the right of the brake pedal (Fig. 2).
The hand control is the upper lever above the steering wheel. Both controls
operate the same throttle; the hand lever, however, remains in the
