.... 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.
Yes simplicity comes at a price, one that is probably worth paying given relatively small sums involved.
The Rotax carbs do have some altitude compensation but it is a primitive mechanical system. I sometimes wonder how rich or lean the engine really is.... and then I just go back to flying.
now back to the regular LOP debate.
