What performance changes should I expect after installation?

Installing a properly matched carburetor restores predictable throttle response and improves starting reliability. While not a performance modification, it brings the engine back to intended factory behavior when the original carburetor has worn or clogged.

• Smoother idle and faster, more reliable starts under normal conditions.
• More consistent power delivery across throttle range and fewer stalls.
• Reduced fuel overflow and improved fuel-air mixture control when installed and adjusted correctly.
