If the wheels or radius rods have too much motion due to wear it may cause vibration at certain speeds and
again it may not. However, they should not be allowed to remain loose, as this condition increases the rapidity of the
wear.
By the rear axle thumping is meant a dull knock at regular intervals. Such a knock might be caused by
broken balls and broken gear teeth or a nut of the differential bolts striking the casing. If there is one thump for each
revolution of the rear wheel it may be that a gear tooth is broken on the main driving gear. At least it proves that the
knock is caused by some part of the axle, which turns at the same rate as the rear wheels. If the noise occurs at
intervals faster than the revolution of the rear wheels it is probable that it is caused by a broken tooth on the pinion
driving gear.
A great deal could be written about this subject, but for the purpose of operating the White Car a few facts
are sufficient.
In order to obtain the greatest mileage from a given amount of fuel we should have the best combustion
possible. Combustion is the chemical union of the oxygen in the atmosphere with the materials used for fuel. To
obtain the best combustion there should be just the right amount of gas mixed with the correct amount of air and this
mixture will produce the greatest amount of heat. However, unlike the internal combustion motor, there is a much
wider range through which the mixture can vary without affecting the final results to any appreciable amount, but
there are certain wide limits within which we must keep to get the best results. These limits we have designated under
the heads of portion of air too great and portion of gas too great.
If the proportion of air is too great the resulting flame has a very light blue color and leaps high off the
burner. Sometimes high enough to be above the lower coil. Naturally, this condition would not be such as to give the
greatest amount of heat to the coils. A great deal of the heat is wasted by the fact that the combustion takes place at
such a high point in the coils. This condition is apt to cause the front seats of the car to become heated. As has been
mentioned, the cheaper grades of fuel commonly known as stove gasoline will give better results than the more
expensive ones. Most of the items given on the chart are due to either making changes or incorrect adjustments.
Too great a proportion of gas for the size of the mixing tube or for the air that can flow into the mixing tube
gives a very red flame, which hangs low on the burner. The amount of air depends somewhat upon climatic
conditions and altitude. The colder the atmosphere the greater the amount of oxygen drawn into the mixing tube, the
inlet remaining the same, and vice versa when the atmosphere is warm or the altitude is high. The correct color of the
flame is a purplish blue slightly tinged with red. The flame should not lift over one half of an inch above the burner
slots. The following rule will hold good under most conditions. The lighter the mixture the higher and bluer the flame.
The richer the mixture the lower and redder the flame. Keep the shutter closed as much as possible without causing
howling or back firing. This condition seems to give the best results.
This is a disagreeable condition and is entirely unnecessary. The packing in the pilot light adjusting valve
stuffing box may leak. The gas escaping through rises outside the pilot light without igniting and sometimes can be
smelled from the seats of the car. To test for leakage, apply a lighted match while the pilot light is burning. Also
should the flow motor fuel valve or the warming up valve be leaking the smell of gas may result. The leakage being
so slight the gas draws upward from the nozzle of the vaporizer instead of entering the mixing tube.
