What It Is

This is a complete carburetor assembly for Honda GCV135, GCV160, GC135, and GC160 engines, commonly found on push mowers like the HRB216 and HRT216. It replaces OEM part numbers 16100-ZMO-803, 16100-ZMO-804, 6212849, and 7862345.

Fitment & Compatibility

Before buying, verify your engine’s model number (stamped on the engine shroud or valve cover). This carb fits Honda GCV135, GCV160, GC135, and GC160 engines only—not the larger GCV190 or GXV series. Check your mower deck size (21–22 inch decks are typical for these engines) but the carburetor itself is engine-specific, not deck-specific. This is an aftermarket part, not OEM Honda. Measure the mounting bolt centers (approx. 60mm apart) and compare to your old carb to confirm physical fit. Also, ensure the throttle linkage style matches your engine (some early GCV160 models use a different linkage).

Key Things to Know

• Quality varies: At $14.99, this is a budget aftermarket carb. It may need minor adjustment to the float height or idle screw out of the box. Some users report it works fine, others need to clean debris from jets before install.
• Installation is moderate: You’ll need to remove the air filter housing, fuel line, and throttle cable. No special tools required, but be careful with the small gaskets and thin mounting bolts. A torque wrench is not necessary—just snug evenly.
• Common gotchas: The included gaskets may be slightly thinner than OEM—use Honda gaskets if you have them. The fuel line fitting can be loose; a small zip tie or new fuel line clamp helps prevent air leaks. Also, check that the choke plate opens fully when the lever is in the “run” position.
• Expect to tune: After install, you’ll likely need to adjust the idle speed and mixture screws (if adjustable) for smooth operation. A dirty old fuel tank can clog the new carb quickly—clean or replace the fuel filter.

Should You Buy It

Buy this if you have a GCV135 or GCV160 engine with a non-starting or surging issue, and you want a cheap, quick fix. It’s right for DIYers who can handle minor adjustments and don’t mind aftermarket quality. Avoid it if you need OEM reliability for commercial use or if your engine has other problems (bad coil, low compression)—a carb swap won’t fix those.
