What should I change first in the carb?
High speed bleeds or jets?
One or two sizes if jets?
Bleeds it has .031 in it, next size I have is .035
What would you do first to get AFR closer to the high 11's-mid 12's at highway cruise and WOT?
Pull the plugs and clean them.
Post a picture of the metering block.
Measure the IFR and PVCR holes.
Put 72 primary and go for cruise. Get off idle and primary dialed in first. WOT is jet the secondary for best mph at the track.
Here's a link to tuning. Follow this procedure and you can dial in the tune: Carb Tunning
