Yes, I know that one doesn't. I just wanted to advise as an "FYI" that carbs that do have replaceable air bleeds, such as the Holley Street HP series (great carbs), are very responsive to changes in the air bleeds which yield the changes the OP is seeking; leaner A/F ratio in cruise circuit without changing the rest of the a/f curve.
PS. I don't think you have anything to really worry about with a 10.8/1 a/f at cruise, re cylinder washing out, but it's not optimal of course. I ran a set Weber's that had a rich cruise a/f ratio, but after thousands of miles there was no change in cylinder wall wear.
