Show Uninterrupted Supply of Fuel in Carburetor It sometimes happens on cars where fuel is fed by pressure supplied by the exhaust gases that it becomes in'vcas-creasingly in'vcas-creasingly difficult to maintain the pressure at the requisite figure. As a rule pressure does not drop quickly, but seems gradually to ooze away. The first tiling to do in a case of this kind is to examine the filler cap of the tank. A leather or rubber gasket is used at this point, and often the rubber becomes be-comes spungy or the leather gets hard and caked, or a small hit of foreign mailer may have lodged between the cap and its seat. On the oilier hand, it cornet imps occurs that the pressure In the system Is built up to a point where the small valve operated by the carburetor float will be unable to restrain the fuel and flooding of the instrument will result. As a rule a pressure of one and a half pounds is ample to insure an uninterrupted sup-l sup-l ply of fuel in the carburetor. |
