How does carburetor causes problems?

The carburetor is connected to the engine at one end which is discharge. It has two suction poles at the other end which are fuel tank and air passage. The carburetor sucks oil and air from its suction gate then it filters the fuel and air in two different filters. After filtration, it mixes the fuel and air and passes the mixed components to the engine.

This is also important to know carburetor itself doesn’t do these things. The process begins when the engine starts. When the engine runs it always keeps sucking fuel from its intake valve.

What causes troubles in the carburetor?

The carburetor has several poles to suction and discharge. If any pole is blocked, the others don’t work. The air filter blockage is the reason air suction valve doesn’t work. You can easily find a foam spiral filter at the air passage of the carburetor.

Air passage

It’s often enough to clean air filter without replacing this. The air filter can be cleaned with water. You can use a synthetic cleaning agent to clean the filter. If the dust and dirt are gustily attached to the cavity of the filter, you can use a brush to break down the blockage.

If the air filter is broken or the paper foam on it looks torn, you should consider replacing this with a new one. Because a torn air filter will take much dust in it and then push into the engine. This is how the engine becomes dirty. The cylinder inside the engine needs to be clean to make effective combustion. If the place isn’t clean enough, it might backfire and stop all of a sudden.

Oil passage

The oil passage valve can be blocked by the sediment that is lying at the bottom of the fuel tank. This is the right time you should focus on your fuel tank. But before you does that make sure how the oil filter is blocked. Detach the oil line between the engine and the fuel tank.

You will see the filter in the carburetor. Check if you see any sticky dirt on the filter. If you find the same, you can clean this with some filter cleaning spirit. Don’t use water or soap to clean this. Remember, moisture can be harmful both for the carburetor and the engine. Oil engine can be replaced by a new one. If your oil filter is continuously being dirty, it’s important to check the oil you are using. Low-quality oil carries contamination that later lies at the bottom of a container.

The metallic carburetor can be cleaned physically by octane or dry nitrogen. For your personal satisfaction, you can clean this if it is too dirty to be looked old.
