Now ya wanna fly..???? LOL..yup used to live at altitude.. uhhhhhhhh dunno bout airplane carbs tho..??? uhhhhh again.. altitude usually changes more the air mixtures...less air at altitude...you can compensate tho for that with timing..if i remember right ya advance timing 2 degrees for each 1000 foot.. smaller jets help the higher ya go too.. as for adjustable..?? the best answer would be a turbo...then ya dont hafta worry bout no stinkin altitude....hehehehe
