So presumably the options are; make spacers to correct angle of installation, which then gives problems with throttle actuation or do what steve downing did and instal a spacer on the rear and deck the front bowl a little: http://members.boardhost.com/GT6-Spitfire/msg/1174009303.html or do as nick jones suggested and run a pair of HIF's... which would probably be the best solution, and maybe the easiest too.

Can't be down to the level of installation. The fuel level in the bowl is directly regulated by the float and jet - its entirely independent of the other carb. Shouldn't matter if the difference in height is 1/8th or a foot! (assuming both are upright enough to operate correctly) Like james says... check the float height. Jon
