This answer was rated:

Are there instructions for carb kit 31840? Specifically, which way is the needle seat installed into the carb? Also, there is a small flat rubber washer (not the O-ring) in the kit. Where does the small flat rubber washer go?

One side of the seat has a shallow circular depression. This side goes in first against the carburetor body. This book will give you complete instructions. Please let me know if anything isn't clear and I'll clarify for you.


Hope this helps!
