Ok a side shot showing the cut out the 33 takes a 6.0 slide the 35 air stryker takes a 4.5 what that means is it will influence the calibration in the area of 1/8 to 1/4 throttle. What the CUT-AWAY does is change the air velocity over the MAIN NEEDLE JET which changes when the MAIN SYSTEM begins delivering fuel. If the transition is lean change the throttle valve to a valve which has less CUT-AWAY (lower number). If this range is rich use a throttle valve with more valve CUT-AWAY (higher number).
Numbers range from a "0" to a 9.5. The 33 and 35 air striker should only use a 4.5 as the lowest and 7.0 as the highest. I was told that the fins on the air strikers help direct the air over the main which increase velocity over the main.

The 35pwk non quad vent non air striker has part numbers from 0-9
