How to Clean a 1996 Sea-Doo Carburetor

Sea-Doo carburetors, like all carburetors, can become clogged with dirt and grime.

Regular cleaning of the 1996 Sea-Doo carburetor will maximize the performance of your personal watercraft and extend the life of its engine. The carburetor is a device within the engine's fuel system that combines fuel and air to create internal combustion. When the device is clean, the engine will start without hesitating, idle smoothly and will not stumble when accelerating. A dirty carburetor can result in an inefficient fuel mixture of too much air and not enough fuel, or vice versa.

Things You'll Need

• Solvent
• Compressed air
• Pipe cleaner

Instructions

1. Remove the carburetor from the engine block.

2. Remove the air vent tube support and the air intake silencer by removing the silencer's cover, unscrewing the plate and base, and removing the flame arrester.

3. Turn the fuel valve to the "off" position.

4. Disconnect the pulse line and fuel supply line from the fuel pump.

5. Disconnect the fuel return line, oil injection pump cable, throttle cable and choke cable.

6. Remove the screws and lock washers retaining the carburetor if you have a twin carburetor model. If you have a single carburetor model, remove the four bolts and lock washers from the rotary valve cover and then move the carburetor and rotary valve on the top of the engine.

7. Remove the carburetor from the intake manifold.

8. Submerge the carburetor or carburetor parts in a bucket of cleaner for 30 to 60 minutes until the grime is dissolved, taking care to ensure there are no rubber or plastic parts attached that might be damaged by the solvent.

9. Scrub all accessible surfaces with a toothbrush or a pipe cleaner under running water.

10. Dry the carbureator with compressed air until there is no water on it or in its passages.

11. Inspect the parts of the carburetor for corrosion damage before re-assembling it. If necessary, replace any worn parts.

Tips & Warnings

• Be careful to not remove paint during cleaning, as this can cause the carburetor to rust. If necessary, repaint the carburetor after cleaning.

• Do not use a flammable solvent with a low flash point, as it could be flammable or explosive.
