Sounds like that would be a good reason for aircraft engines to to have EFI. Not arguing just making an observation. Some people say rotax may be on the way to phasing out the carbs in favor of the EFI and ECU. Maybe who knows.I won't go into the (significant) differences here between car engines and aircraft engines as I'm sure Dean already covered that with you down at Lockwood, but the biggest reasons cars don't have carbs any more is emissions and mileage standards.
I agree . Rotax probably has to much invested. That would be an expensive move.If aircraft emissions were a major consideration, we'd all just stop using leaded fuel, for starters. If fuel economy is very important to you, you'll certainly do better flying an airplane.
Rotor hasn't even phased out two-stroke engines. I don't see them phasing out carbs any time soon.
