Reply To: Resizing UU-2 main jets

[Edgar Minnie]

You are correct that the carb is often plugged in the internal passages and most people can’t get the plugs out to clean them. It is NOT easy to get them out. The UUR2 is much improved over the UU2. Interestingly there are FIVE diffrent UU2 bodies, and three diffrent UUR2 bodies, and they are not all interchangeable, but the “odd” ones are rather rare. Cleaning the unit and replacing worn shafts that leak air is 50 percent of thr battle. Getting correct internals is the other 50. John is a great resource and makes most every part you will need. Be sure to rebuild your fuel pump and clean the gas tank, or you will get to do the job over………..several times!
