Answer
Hello Dave:

Here is the Information you Requested. ****The Operational/High RPM Air Mixture Screw is In the Carburetor Bowl in the Center of the Nut or Some Carburetors have Both the Idle Air and Operational Air Adjustment Screws Side by Side on the Top Side of the Carburetor. The Screw Closest to the Engine Is Usually the Operational Air Mixture Screw on this Type Carburetor.The Idle Air Mixture is the One at Top on the Side and Goes Into the Carburetor.   Some have the Idle Air Mixture Screw Going Vertically Into the Top of the Carburetor. The Engine Idle Screw is the One that Moves the Throttle Plate. The Following is the Directions for Setting these Screws. **If the Carburetor was Soaked Overnight in Carburetor Cleaning Solution and the Passages Blown Out with Compressed Air and a New Kit Installed,  then we can Set the Air Mixture Screws. Turn Both Air Mixture Screws In Until Seated. **DO NOT JAM  SNUG ONLY** Turn Both Screws Out 1 1/2 Turns. Set the Throttle to Full Open and Start the Engine. Override the Throttle by Pushing the Governor Arm by Hand and Turn the Operational/High Air Mixture Screw(bottom of the bowl) In Until the Engine is Revving Properly. Now Slow Engine to Idle. Set the Idle Air Mixture Screw so there is No Hesitation when Throttling from Idle to Full Throttle. Now Set the Engine Idle if Required.**** Hope this Helps. I am here if you Require more Assistance. Let me know what Happens, Please. Thanks.

Good Luck
