On being fitted with 'NER-MIS' has just completed 7,000 miles and the plug only removed once to adjust points. 9. CEMENT MIXER. A plug with water on and around insulator will usually fail to fire, but has been found to keep firing with 'NER-MIS' fitted and the hose-pipe turned full on and the water covering the adaptor and plug. 11. AUSTIN 7 HP. An Austin 7 HP. 3 months old was taken back to Austins service depot 3 times owing to a hunting engine and flat carburettion spots and no improvement was made at any time. Fitted with a set of 'NER-MIS' the engine ticked over evenly and flat spots gone. Owner has used this car for 5 months with t'e adaptors fitted and says that he gets better hill climbing and general satisfaction from them. As soon as the adaptors are removed he gets his old trouble back again and has to keep changing speed. 12. VAUXHALL. Harry's Garage, Laindon, Essex. Vauxhall with 4 plugs out of 6 would cut out with oil in less than two minutes, and would cut in again when fitted with 'NER-MIS' and would continue to fire indefinitely. On removal of the adaptors the engine at once stopped. | ||
