.... and whilst flying your Rotax you are wasting up to 25% of your unleaded or Avgas fuel due to the lack of altitude compensation in your twin Bing carburetor set-up! With the simplicity, also comes a manufacturer built in nufty buffer which isn't your fault but it costing you money.
(Of course please ignore that if you are running a 912 IS model)
