| BIG END BEARINGS. Interesting in that the sideways location is on the steel rod instead of white metal. This gives a greater effective big end length, stronger rod and a much cheaper construction. Carburetter with Cent. Blower. Graham Paige have found it desirable to use a plain choke carburetter with the blower. They state that at low speeds the blower is highly sensitive to any depression on the suction side, and also the depression is not needed with a blower for snap opening-up. They tried an expanding constant-depression type of carburetter but found they lost their boost from 1000 to 1800 R.P.M. Another advantage of the fixed choke carburetter is that it tends to reduce boost where too much is not wanted i.e. at maximum speed. Starting, Warming up, Snap Acceleration, Slow Running They claim that the centrifugal blower has improved all these features, Certainly the finished car behaves in a refined manner. They have eliminated the exhaust heated hot spot. TV | ||
