Product Overview
When an older Kohler engine hunts, floods, leaks fuel, or will not take throttle, years of deposits and throttle-shaft wear can make the original carburetor difficult to save. This replacement is meant for restorations and working equipment that need predictable fuel delivery again.
K-series engines were produced in more than one specification. Check the engine model and spec tag, then compare the mounting flange, choke direction, throttle linkage, and fuel inlet with the carburetor being removed.
This is a high-quality aftermarket replacement or service part and is not manufactured or supplied by the original equipment brand. The names below identify compatible applications only.

Frequently Asked Questions
Q: Will this fit every K181 engine? A: Not automatically. Kohler used different carburetor arrangements by engine specification, so the original number and physical layout must match.
Q: Can a bad carburetor make the engine surge? A: Yes, but a governor problem, intake leak, restricted fuel cap, or dirty tank can cause similar symptoms.
Q: Is adjustment normally required? A: A baseline setting may be present, but final idle and mixture checks should follow the Kohler service information for the engine.
