How are leaks and jams in the Radiator repaired?
Answer No. 41
While the stopping of one tube does not seriously interfere with the circulation, it is bound to cause
trouble sooner or later---and the tube will freeze in cold weather. Cut the tube an inch above and below
the jam and insert a new piece, soldering the connections. If the entire radiator is badly jammed or
broken it would probably be advisable to install a new one.
The Ford Gasoline System
The Carburetor---how does it work?
Answer No. 42
The carburetor is of the automatic float feed type, having but one adjustment---the gasoline needle valve.
The cross-section diagram of carburetor below shows how the gasoline enters the carburetor, is
vaporized by a current of air and passes through the inlet pipe to the engine in the form of an explosive
mixture. The gasoline, entering the bowl of the carburetor, gradually raises the float to a point where the
inlet needle is forced upwards into its seat, thus cutting off the flow of gasoline. As the gasoline in the
bowl recedes, the float lowers, allowing the needle to drop from its seat and the flow of gasoline is
resumed. It is plain to see that a constant level of gasoline is maintained in the carburetor by the
automatic action of float and needle. The quantity of gasoline entering into the mixture is governed by
the needle valve (see Answer No. 45). The volume of gas mixture entering the intake pipe is controlled
by opening and closing the throttle, according to the speed desired by the driver.
