if you adjust your jets down to get a good cruise AFR and your WOT goes too lean you need to enlarge your powervalve restrictors. To get a good baseline for tuning your air bleeds and emulsion circut you'll need to be able to get some good data logging. Also, your accel pump shot can be adjusted with squirters and cams, this is one of the last steps though.

BTW, once the weather changes 15 degrees you'll get to do it all over again! Aren't carbs fun?
Just a blast lol what do u think of the 4150 HP? I just want it bc it seems a lot more tuneable to me with the screw in air bleeds and I think my motor could benefit from the 750 cfm instead of the 670
