[QUOTE="swampratt, post: 3102064, member: 15054"] there are auto carbs very similar to the economizer type in aviation seen at the top of this link. [URL]http://www.flight-mechanic.com/float-type-carburetors-economizer-system/[/URL] Where mechanical linkage moves the economizer needle out of the jet or into it dependent on throttle angle. They do not seem to be much different really from the auto carb. But the auto carb needs the needle moved in and out of the jet or fuel passage many more times than the aviation carb due to stop and go driving and flat and hilly areas and passing and cruising. In the air you are steady state cruise. Could you imagine how much in an automobile you would have to pull the lever in and out just to make it to the store with the correct air fuel ratio. I would think you have exhaust temp readings so you know if you are rich or lean in an airplane..But i do not know. [/QUOTE]
