I have yet to try them but will next week or so and will report back.My 1921 2-speed Sparkbrook motorcycle - with a 269cc Villiers engine - when fitted with a Lodge 3-electrode plug would just climb the steepest hill in the district. With a single electrode plug fitted, one had to get off and run alongside. I've never noticed any difference in performance on other vehicles with triple or single electrode plugs, so it may well have been this early and crude deflector-piston two-stroke engine was just suited to them.
