I've rebuilt a bunch of the M/S originals, unbranded replacements, and a Zenith replacement. Most tuned and ran like a new carb. The plain case replacement carbs are always of inferior quality. All you have to do is look at the castings and how they were finished. The machine work is always poorly done. Most of them can still be rebuilt, and they will work just fine. One of the unbranded smooth case replacement carbs I rebuilt did not work. I took it apart and went thru it again, and that particular carb still would not run right. I could get it to idle fine, and run high RPM, but it would not transition from idle to main jet without stumbling, unless I advanced the throttle painfully slowly. Finally took it apart, salvaged everything for spare parts, and tossed the top and bottom castings in the trash.
