-2- This compares very favourably with tests we have carried out with Delco-Remy, Bosch, and Lucas distributors. In view of the fact that this test practically represents 15,000 miles running on a car, we consider that the points on the new distributor should run 20,000 miles without attention. This is a considerably better life than that obtained with the present standard distributor contact points. It was noticed that the thin bakelite rubbing block tends to squeak very badly unless the cam is kept well lubricated. This may be due to the rubbing block itself vibrating, but we think an improvement might be effected if some positive lubrication of the cam was possible, in the shape of a small lubricating felt pad. We have noticed that Messrs Lucas have now adopted this method of lubricating their double breaker distributor cam. On the whole we are very pleased with this new design of distributor, and consider it a definite step in the direction of improved performance, and reliability for the R.R. battery ignition. We are carrying out further tests with this distributor in order to ascertain how far the maximum speed range has been extended due to the use of the three lobe cam and double breaker.
