Specs At A Glance

Good To Know

Q: Will this carburetor need adjustment after installation? A: Most units start on the factory settings and only need fine tuning of the idle and mixture screws. Adjust after the engine reaches operating temperature for the best result.

Q: Should I replace the fuel lines and filter at the same time? A: Yes, old lines and filters can shed debris that quickly clogs a new carburetor. Replacing them together protects the new unit and improves reliability.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
