My John Deere 2020 carburetor dried out and was leaking gas from three different locations.  I bought a re-build kit and pulled the carburetor.  After looking at the rebuilding kit it became apparent to me that having someone else with more experience re-build the carburetor was the wiser path to pursue.  I took the carburetor and re-build kit to Cazenovia Equipment Corp. for them to re-build and re-assemble on the tractor.
