About this part

The GX240 and GX270 are the 8 and 9 HP engines behind a lot of pressure washers, tillers, pumps and go-karts. This carburetor replaces 16100-ZE2-W71 and 16100-ZH9-W21, and it comes with a new air filter so the intake is fresh on both sides.

It is manual-choke only. If your engine has an automatic choke, or your generator needs a fuel-cut solenoid on the bowl, compare your old carb before ordering.
