• Clean the carburetor body, jets, and all the air passages in body with carburetor cleaner.
Note: It may be necessary to soak parts in a high caustic carburetor cleaner.

Instead, clean rubber parts with mild detergent and hot water.
• Use carburetor cleaner or contact cleaner to check passages in body making sure that they are not obstructed.
• Use low-pressure air to dry all components.
Replace parts in proper order:
• Install pilot jet needle jet, jet holder, and main jet.
• Install needle valve with fl oat sliding pin locating in place.
