These results appear to clearly indicate that a lower capacity condenser is desirable to eliminate point oxidation. It may be also that the capacity of the condenser and the inductance of the ignition coil must have some particular relation to one another in order to obtain satisfactory tungsten point performance. This was emphasised by Mr. A.P. Young some time ago in connection with tungsten points on magnetos. Tests with lower value condensers are proceeding. HEWest. | ||
