I understand that Van's doesn't support the Fuel Injected Rotax. Is one of the reasons for this, Fuel Injection is more complicated than the carbureted engine and therefore more potential for failure. I know Fuel Injection requires electronics and a high pressure pump that isn't needed with a carburetor. My experience with carburetors is as long as you have suction from the pistons pulling in air, ie. the engine is running, they operate. I'm all for keeping things as simple as possible.
