We notice on the latest scheme for the Battery Ignition that the vent for the high tension distributor is similar to the ones we are now running. We have found this vent entirely inadequate. After a set has been run for 300 to 400 miles the whole of the parts inside the high tension distributor are covered with green verdigris. We consider that we shall have to have definite holes in the compartment containing the high tension rotor. Hs. {Lord Ernest Hives - Chair} | ||
