Dave:

- MAB .033" to .036" swap: Once I can test drive the .036 MAB's and write down any changes at cruising speeds, then I am going to test the cruise to WOT affects. I did not change any jetting, only the secondary pump cam change from red to pink (due to the rich spike right at WOT kickdown. The pink should lean that spike out). This test should help me decide if I need to make any changes on my secondary jetting.

- I am content with the .031 IFR swap. I think that it puts me right on the richer limit for the cooler Spring and Fall temps. I would like to lean out the 14.6 cruising readings from 25mph to 50mph just a tad, so I might try swapping out my .071 IAB's to some .073's after my MAB test. But the combo of .031" IFR's and the .071" IAB's might be my cool weather ticket. (I currently have .067's, .068's, .071's, .073's and .075's to play with.)

Thank you for your reply and I will post my results once the weather breaks.
