I have had my fill of Chinese clones. tried a few/ yeah, they're cheaper than a rebuild kit for an original carb but I was getting what was paid for.... yeah the engines would run, but not run well, at one condition or another. I'll deal with bushing throttle shafts if that's what it takes.... wanting (preferably" the #26 version, need one for an older Cub 12hp application (tractor number 129 or older) as the air filter housings are slightly different to the newer ones, and the mouth of the older carbs are different to mate up.
