A CORNER FOR THE j OWNER WHO WANTS TO 1 PUT SMALL JOBS RIGHT HIMSELF ] HINTS BY “HEADLIGHT” A 1922 Nash ran perfectly at speeds under 30 miles an hour. Above 30 miles an hour the engine stopped firing as suddenly as though the ignition switch had been turned off. After coasting about 100 feet or so the engine started firing. It fired for about 200 yards, when the engine stopped firing again. This disturbance kept up as long as a speed above 30 miles an hour was maintained. Upon decreasing the speed slower than 30 miles an hour the engine ran perfectly a-rain. This was fuel trouble. The valves in the vacuum tank did not operate properly at speeds above 30 miles an hour. Due to the increased suction from the engine they allowed gasoline to overflow the vacuum tank. The engine drew in a large quantity of gasoline which made an extremely rich mixture. This caused it to stop firing. When the surplus gasoline wardrawn off the engine started firing. As soon as the vacuum tank overflowed again the engine storied firing. At speeds under 30 miles an hour the valves in the vacuum tank worked properly because the suction from the engine was less.

When a new tank head, including r alves, was installed, the trouble \va: •vercome.
