    Why don't more folks use a primer with the 912? It would seem to me that the use of a primer would help greatly. In fact, I fly a 912UL powered Skyranger that uses only a primer and no choke. My primer works by injecting fuel into the manifold pressure output port and works well. The Bing carbs have primer ports and and I do wonder why they are not more widely utilized. It would seem to me that both a primer and choke would be best in cold weather. Read this topic online here: http://forums.matronics.com/viewtopic.php?p=276253#276253

    If you live in a cold climate the best thing you can do for you engine is get a pre-heater. Heating just an oil tank on the 912 is no good because it is a dry sump. You need to heat the cylinders, block and oil tank. The engine metals on a really cold start are not a good thing. I just installed another pre-heater in for another 912 owner. On a day when it is in the teens the engine is 85F with a good pre-heat system. -------- Roger Lee Tucson, Az.
