How does the pilot screw adjustment carburetor work?
Pilot Screw Adjustment Carburetors control the amount of air and fuel entering the engine to provide the correct mixture for combustion. To do this over a wide operating range, multiple fuel circuits are employed. At idle and low throttle openings the pilot, or slow fuel circuit, plays the most important role in fueling.
What’s the proper way to adjust a carburetor?
Consult the service manual for proper instructions. Drill into the plug using a drill stop so you don’t go overboard and hit the adjusting screw. Thread in a self tapping screw and pull out the plug. To turn the screw a special wrench may be required. Also, the carburetor must be mounted in place when adjusting the screw.

Which is the pilot adjusting screw on the KZ1000?
On the left is the pilot adjusting screw from my original carbs. On the right is the pilot adjusting screw from the spare carbs.

Any one have a clue to which one I should use?
