Carburetor Model Information GBO/C70 carburetor model. Screw hole size for mounting the carburetor: 6mm. High-quality products classified as Grade A, with quality similar to original Thailand/Keihin QC standard.
This carburetor mounts backwards under the fuel tank on a ATC 70 three wheeler. It is not OEM here in the U.S.A. That means fuel shut-off and choke is on the RIGHT side if your sitting on the bike. Little confusing at first, but works as it should.
