Because they work. ?The CV carbs used on the Rotax engines require a lot more maintenance than either the RSA fuel injection or MS carbs found on a Continental or Lycoming. ?Also, while Bing claims to be self adjusting for altitude (I believe the actual wording is Altitude Compensating)... Well, they kind of do that, but try taking a Bing from sea level to 13,000' or higher. ?It works, but not particularly well. ?RSA fuel injection and MS carbs give you fine control over your mixture and will run properly up to any altitude that your engine can make enough power to hold you aloft. ?But you can bet that with either the MS carb or RSA injection you are getting the best performance at altitude your engine can provide. ?A CV type carb doesn't do that. ?The fuel distribution is less than optimal from the MS carbs (as well as the Bing carbs) or any other carburetor but the RSA fuel injection addresses fuel distribution to the cylinders, and can even be tuned to compensate for uneven intake velocities. -Jeff Scott Los Alamos, NM > ----- Original Message ----- > From: Nerobro > Sent: 06/20/13 07:57 AM > To: KRnet > Subject: Re: KR> Broke My Plane, a little Mixture setting > > I have always wondered why lycoming and continental have steadfastly stuck > to ancient carb (and fuel injection) tech. ... i think rotax is running > cv carbs on the 912 which is nice.
