Important Buyer Notes

• Visual Verification Required: Kohler Courage engines utilized multiple carburetor variations depending on the exact specification code (e.g., SV600-0025 vs. SV600-0200). Please verify your original unit's fuel line inlet angle and throttle linkage position against our product photos before ordering.

• Governor Linkage Handling: Take careful note of the choke and governor spring placements during teardown. Misaligned springs can cause unsafe engine over-speeding.
