Barrett Small Engine

Okay, today I'm going to show you how to find the model number on a Zama carburetor. I'm going to start with older carburetors from the late 1970s and early 1980s. As the years have gone by, the location of the model number has changed. Engraved Model Number In the late 1970s and early 1980s, the model number was engraved into the carburetor. For this particular carburetor, the engraved model number, 1701C, was engraved on the body of the carburetor. At that time, it was also sometimes engraved over the choke or throttle valve. You can see it here as H18. After that period, the location was moved near the fuel line connections. Some people misinterpret these castings, where there's a number such as C1U, as being the model number. Or they'll see an H and then a number and think that's the model number. The model number will never be cast into the body of the carburetor. The number you're looking for on older carburetors will be engraved. Laser-Etched Model Number...
