How does the accelerator pump improve engine performance?

The integrated accelerator pump provides an immediate burst of fuel when the throttle opens, which reduces hesitation and improves throttle response under load. That makes acceleration smoother and helps avoid stalling during quick speed changes.

• Delivers extra fuel on throttle onset to prevent lean hesitation.
• Improves responsiveness when engaging blades, loaders or heavy attachments.
• Helps maintain steady idle-to-throttle transitions for smoother operation.

What should I know about installation and maintenance?

• Recommended to use new gaskets and mounting hardware for a leak-free seal.
• Inspect fuel lines and filters while the carburetor is off the engine.
• Adjust idle and mixture screws per Kohler specifications for optimal performance.
