Fire Will Not Come On Without Racing Engine - White Motor Company White Steamer M Service Manual

on the water regulator pin, the back pressure will keep the flow motor from closing properly, causing the fire to burn
slowly to a more or less degree. On the other hand, if the packing in the flow motor stuffing boxes on the fuel stem
piston rod is too tight, the flow motor may in extreme cases refuse to close and the fuel will continue to feed,
regardless of the action of the water regulator. In connection with this it is worth mentioning that the fuel stem being
bent or broken, or a broken spring inside the flow motor (very rare) would give exactly the same result. Occasions
have occurred when the hand fuel valve was leaking slightly and the fault was laid to the flow motor. A good way to
detect leakage when it is too slight to cause a flame above the burner is to apply a match to the vaporizer tip.
Immediately after stopping the flow of fue1 there is always enough gas to support the flame for a short time, but if the
hand valve and the flow motor valve are seating perfectly, this flame should burn out for lack of gas. If it continues to
burn, and blows occasionally, either the hand fuel valve or the flow motor valve is leaking, If the valve operated from
the seat is closed, and the flame goes out, the chances are two to one that it is a flow motor gas valve leaking. Never
try to grind this valve for leaking. Grinding material will spoil the lap fit. An easy way to stop this valve from leaking
is to form a seat by tapping the head of the valve by means of a small hammer and punch, care being taken not to tap
too hard and to turn the valve stem around at short intervals.

FIRE WILL NOT COME ON WITHOUT RACING ENGINE.

We have divided this condition in two features. Take notice if the car has wet steam or dry steam. If the steam is dry,
It shows a deficiency in the water supply to the generator. In this case it is best to first be assured that the water can
get to the pumps. This can be brought about by inspecting the water tank to see if it contains water, the strainer in the
bottom of the tank to see that it is not clogged, or the hose leading from the tank to the pumps, that it is not soft or
clogged. All these conditions have been described under the head of lack of power, but dry steam. Under this heading
of dry steam there are but two places where the water can go if the pumps are pumping normally, through the water
regulator bypass and the flow motor bypass. This can be quickly determined by breaking the unions respectively on
same.
On the other hand, if the steam is wet and the fire does not come on, the chances are greatly in favor of the
fact that the water is passing through the thermostat when it should not be doing so, thus causing the water to
overbalance the fire. If the thermostat is set too low it will give this same effect after the car has been running a few
minutes. In case the fire refuses to come on, the first thing to do is to look at the flow motor. If the flow motor is not
opening, then the above mentioned circumstances hold good. If it is open and there is no fire, look for a dry gasoline
tank, a clogged vaporizer or a choked gasoline supply somewhere. There maw be the possibility that the hand fuel
valve has not been opened, as is often the case with a "green hand" operating the car.
