Hello, I own a moped Ogar 205 for which I just purchased this carburetor.
I can consider the quality of workmanship of this carburetor from duells company as satisfactory because there are no problems with leakage from under the flap of the float chamber and with the adjustment itself because the factory-installed nozzle is sufficient, and the carburetor itself responds to adjustments, which I have not experienced in cheaper substitutes.
