There is no mixture control on a Rotax with Bing carburetors.

Was referring to the aftermarket solutions available, which to my understanding regulate float bowl pressure in order to lean the mixtures.

Not sure what aftermarket solutions you're referring to but why would you want to replace standard Bings anyway?

You don't replace the Bing carbs. The HACman® High Altitude Compensation/Manual Mixture Control for Rotax 2 stroke is a valve connected to the carb bowl vent that meters air going into the bowl. By reducing air pressure in the bowl the mixture is leaned.

Have installed several 912's...good solid number firewall forward, radiators, hoses, coolant...everything but the battery to crank it and fuel to run it, 160-165 lbs. Was weighed when a complete install was lifted from a plane, mount included and hung from a scale.
