| -6- bearings is relied upon the drip on to the cam faces working through on to the shaft and through a hole in the shaft, which then feeds the two bearings. This scheme of lubrication must have been altered, for we used to feed the cam bearings irrespective of the cam faces. That lubrication was put on to feed the cam faces only, and requires looking into. Rear axle. There is a bad oil leak working along the o/s driving shaft through into the hub, and draining out by way of the drain. The n/s has remained perfectly O.K. This requires looking into. Clutch. The failure of the cast iron pressure plate seems to be a serious proposition. It is only because this plate has been shrouded by the flywheel that it has not burst and caused serious damage. We think it very advisable to keep to the steel ring, and putting up with a slight scoring of the face that was noticed on the pressure plate of 23-EX. Clutch and brake pedals. The arrangement of the pedals and the anchorage appear to be quite O.K. Carburetter throttle. As reported to you, slightly more load is required on the pull off spring for the throttle. It appears to be on the minimum side of lightness, and no trouble has come from placing the pull off spring in a slightly higher tension. Hot spot (carburation). Assuming that the petrol used in America is similar to the commercial spirit we are using here, the heat to the carburetter hot spot is definitely not sufficient, and if R's recommendation is carried out in regard to keeping the water temperature lower, the performance of the car will be definitely down. We have found that with | ||
