The Honda 16221-ZA8-800 Carburetor Gasket is a genuine OEM Carburetor Gasket designed for the EM650 generator, EX350 inverter generator, and EX650 generator. As a direct Honda OEM component, this gasket is manufactured to the exact specifications Honda engineers set for these units, ensuring a proper seal between the carburetor and the engine. Confirm your generator's serial number against the fitment table before ordering, as Honda supersedes parts at specific serial breaks and more than one variant may be listed for your model.
Key Features
- Fuel-Tight Carburetor Seal — engineered to maintain an airtight, leak-free interface at the carburetor joint, where even a minor gap can disrupt the air-fuel mixture and cause hard starting or rough running
- Genuine Honda OEM Part — sourced directly from Honda, part number 16221-ZA8-800 carries the same specifications as the gasket installed at the factory, so there is no need to second-guess material thickness or fit
- Fits EM650, EX350 and EX650 Generators — confirmed fitment across the EM650 generator, EX350 inverter generator, and EX650 generator; verify your serial number against the fitment table to ensure this is the correct variant for your unit
- Restores Proper Fuel Metering — a cracked or compressed original gasket allows unmetered air into the fuel circuit, leaning out the mixture and robbing the generator of stable output; replacing it with this part brings the carburetor back to spec
The carburetor gasket sits between the carburetor body and the engine's intake port, forming a seal that keeps the air-fuel mixture at the ratio the carburetor is calibrated to deliver. When this gasket deteriorates, shrinks, or cracks, outside air is drawn in past the seal, leaning out the mixture and causing symptoms such as hard starting, erratic idling, or loss of power under load. On a generator, where consistent engine speed directly determines output voltage and frequency, a compromised carburetor seal can make the unit unusable for sensitive equipment. Replacing a worn gasket with this genuine Honda part restores the sealed interface the carburetor depends on to meter fuel correctly.
