hello karter”s. Im running a 2013 rotax sr motor wondering whats the optimum spark plug gap. The spark plug is a Denso Iridium IW29. The weather in mostly in the high 80’s and higher in south fl.
It should be between 0.018″-0.025″. You will have to experiment what works best for your engine and the weather conditions for that particular day.
