| R.R. 235A (500 T) (S.D. 408. 26-4-17.) Bm. 2/156/13. -3- 13.3.19. Contd. or the float level. 50% Bensol 50% Petrol.(or 1 tin of benzol to 1 tin of petrol). With this mixture there is a smell of benzol from the exhaust. The deposit in the carburetter and on the inlet valves is apparent but should not cause any harm until after a considerable amount of running. Detonations are completely eliminated. There is no need to make any alterations to the carburetter adjustment or to the level in the float chamber. Starting and slow running are quite satisfactory. It should be noted that to get the best results with benzol and petrol mixtures the mixture control lever on the steering column should be adjusted so that the mixture is as weak as possible without the loss of power.
