Troubleshooting & FAQ

How do I confirm this kit fits my engine?

First, check your engine's model, horsepower, and year of manufacture. Compare this information with the "Compatible Engine Models" table. Second, cross-reference your existing part number (often stamped on the carburetor body) with the numbers in the "Part Number Cross-Reference" table to ensure a match.
