This low-cost carburetor is of very high quality and has a multitude of adjustments: richness screw, idle jet, needle valve ... This model is the AD (also exists in BD, AD, DS, DD, black edition, or BS), it is rigidly mounted with a cable choke, you can also switch it to a lever choke without difficulty.
