How to identify a Zama carburetor

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

For newer carburetors, it will be printed in black ink or laser etched. It will begin with a letter.

On this particular carburetor, it's a K43B. The K denotes it being an Echo carburetor. The K43B should let you find the G&D kit, gasket and diaphragm kit, rebuild kit, or a replacement carburetor.

On the other end, where people misinterpret the model number, you will see the casting number, which is a C1U. That is part of the model number. It will be a C1U-K43B.

The model number itself will always be etched, laser etched, or printed in black ink near the fuel line connections on most newer carburetors.

C1T Model Number

On some carburetors, such as this C1T, the C1T is right here, and then the model number itself is right here as W33C. The date code below it is irrelevant. You don't need to know that number. You just need to know the W33C.

Rotary Model Number

On rotary carburetors, the model number is a little different. It's in the upper left-hand corner, right below where the throttle cable goes into the carburetor. You should usually be able to find it in the upper left-hand corner.

For this particular one, it's a K85. The 1ZA is the date code and is irrelevant. The K85 is the only thing you need.

Some people misinterpret it as being an RB27. That would be wrong. It is an RB-K85, but the RB27 is not the model number.

The model number, again, will never be cast into the carburetor.

Summary

Zama currently is changing part numbers to new part numbers. To help the consumer and the service technician, the new model number will be printed at the top, then the date code, and then the old model number that it replaces will be at the very bottom.

Either the bottom number or the top number can be used to find your rebuild kit or replacement carburetor.

If you pull your carburetor off a unit and can't find a model number on it, you can always email Zama Tech Support or call Tech Support, and we can figure it out for you.

We always offer a service where you can email us pictures of the carburetor while it's off the unit, and we will identify the carburetor for you.

I hope this helps you identify your carburetor. Please like this video if you enjoyed it, and we have several videos on our YouTube channel.
