What is a Carburetor?

A carburetor is a device that mixes fuel and air in the correct proportions to create a combustible mixture that can be ignited by the spark plug. The carburetor is located on the intake manifold of the engine and is responsible for providing the engine with the correct amount of fuel at the correct time.

The Can Am DS 90 carburetor is a two-barrel carburetor that uses a float bowl to maintain a constant level of fuel. The float bowl is connected to the carburetor throat by a needle valve. When the engine is running, the vacuum created by the pistons draws fuel from the float bowl through the needle valve and into the carburetor throat.

The carburetor throat is a tapered tube that helps to mix the fuel and air. The air enters the carburetor through the air filter and is drawn through the venturi, which is a constriction in the carburetor throat. The venturi creates a low-pressure area that draws the fuel from the float bowl into the carburetor throat.

The fuel and air are then mixed together in the carburetor throat and sent to the intake manifold. The intake manifold distributes the fuel and air mixture to the cylinders, where it is ignited by the spark plugs.

How to Adjust the Can Am DS 90 Carburetor

The Can Am DS 90 carburetor is adjusted by turning the idle mixture screw and the main jet needle. The idle mixture screw controls the amount of fuel that is mixed with the air at idle speed. The main jet needle controls the amount of fuel that is mixed with the air at higher engine speeds.

To adjust the idle mixture screw, start the engine and let it warm up to operating temperature. Then, turn the idle mixture screw in until the engine starts to run rough. Then, turn the screw out until the engine runs smoothly.

To adjust the main jet needle, remove the air cleaner cover and locate the main jet needle. The main jet needle is a small, tapered rod that is located in the carburetor throat. Turn the main jet needle in to richen the mixture or turn it out to lean the mixture.

How to Troubleshoot Common Carburetor Problems

There are a number of common carburetor problems that can occur on the Can Am DS 90. These problems include:

• Engine flooding: This is when the engine starts to run rich and the exhaust pipe emits black smoke. This problem can be caused by a dirty carburetor, a clogged fuel filter, or a faulty fuel pump.
• Engine running lean: This is when the engine starts to run rough and the exhaust pipe emits white smoke. This problem can be caused by a faulty carburetor, a clogged air filter, or a misadjusted carburetor.
• Engine stalling: This is when the engine stops running without warning. This problem can be caused by a dirty carburetor, a faulty fuel pump, or a bad spark plug.

To troubleshoot these problems, you will need to first identify the symptoms. Once you have identified the symptoms, you can then begin to troubleshoot the problem.
