| -3- Again the fact of opening the induction pipe cock during retardation and closing again as soon as the throttle commences to open causes the engine to do the same. As it is, after accelerating and retardation the engine misses fire for the first 2 or 3 charges of gas that pass into the engine and then picks up with a jerk or fails to pick up at all, the engine stopping altogether. Again during our experiments with the "fading away" effect, i.e. petrol inertia, a glass window was fitted in the carburetter body showing how the petrol was supplied from the high speed jet, and it was astonishing to see the way the petrol passed through the carburetter in big beads of petrol. The Polyrhoe carburetter which does not have the "fading away" trouble appears to supply the petrol through the | ||
