If your carb. has the screw in removable #10 air bleeds now I would be tempted to buy the pin vice and the small drill bit assortment, #61 to #70 and maybe the bigger drill bit kit from #1 to #60 and see what your current bleeds are, once that is figured out either buy some blanks or the next size bigger bleds and next size smaller and test, test, and test some more to get it exactly where you like the tune up
I ended up buying a batch of 100 # 6 brass set screws and started drilling and tapping the fuel feed channels(idle and transition circuits) for those size set screws and drill them to the size I wanted and found out exactly what the motor wanted judging by the old Butt dyno and the wide band, I now tune for lean(14.8 AFR or leaner) at idle and at light part throttle cruise up to 2500 RPM now at 3500 Ft. elevation on Oregon 91 octane pump swill
