It would be possible to try the effect of slow make and quick break with an experimental cam and we think this would be an improvement from the point of view of noise as well as the reduction of sparking. As regards rigidity, we cannot see from observation that there is much difference between RR and Delco-Remy levers. We are of the opinion that an increased spring pressure will improve the performance of the tungsten points. With regard to limiting the lift of the lever, we would point out that costs Signed This Sheet must be filed on completion of the work. | ||
