Never replace a carburetor for complaint of poor idling or excessive gas consumption without first removing the carburetor and thoroughly cleaning the jets and filter screen. Also remove the brass plug beneath the main jet and thoroughly rinse the carburetor bowl with gasoline, using air to blow out any dirt which may have lodged in the bottom of the bowl.

When removing the carburetor separate the parts carefully to avoid damaging the gasket, float, or idling jet tube.
