FENGCHUNS Carburetor Replacement for Kohler KT730 KT725 KT735 KT740 KT745 22–26HP — Direct-Fit Aluminum with Fuel Pump Kit

FENGCHUNS carburetor replacement is a direct-fit, tested aluminum carburetor and fuel pump kit engineered to restore reliable fuel delivery on Kohler 7000-series KT7xx 22–26HP engines.

If your Kohler-powered mower, generator, or equipment is showing rough idle, fuel leaks, or loss of power, this bolt-on carburetor assembly replaces OEM parts 1685319-S, 32-853-34-S, 32-853-63-S, and 32-853-67-S to bring performance back to specification. Constructed from high-grade aluminum alloy and supplied with a matched fuel pump, the unit is bench-tested for leaks and calibrated to match factory flow characteristics. No extra machining or modifications are required—just unbolt the old carb, attach the provided pump and gaskets, and you’re ready to run.
