The difference is that one carburetor has the idle mixture adjustment at the throttle arm, air-bleed carb has an airbleed screw and a hole in the carb body that has its opening adjusted by the air-bleed screw. If you examine the carburetor, the difference is obvious. Any engine sold in the past several years should have the carb with the mixture control screw and not an air-bleed screw.
