(2) off, and at slow speeds the petrol blimbs up the pipe belonging to the jet and extra trickles back the one belonging to the/air valve, to such an extent as to entirely spoil the mixture when opening the throttle. This may be one of the reasons for the quick sooting up and the poor consumption that this car was giving. | ||
