Kohler CV460s carb replacement John Deere Lt160 tractor

[@dusty1498]

I put one of these replacement carbs on my Lt160 but it constantly hunts/surges i tried adjusting the Low speed screw but i cannot get rid of the Hunting Any Advice?

This is my exact engine. Looks very similar to the replacement carburetor I replaced my original with. There are two screws on it similar to yours. Top silver one with the spring and a black screw. How much should they be tightened/adjusted? Initially it stuttered/hunted like yours did and I can't get the screw adjustment correct between the two. Any suggestions?
