What are the Signs that your Carburetor Needs Cleaning?

There are several symptoms of a dirty carburetor. If you see, hear or experience one of the issues below, Clean-R-Carb™ may be the solution you need. It could save the time and expense of a costly repair and get your car or truck back on the road.

Does your vehicle or small engine make popping sounds? Over time, deposits like gum, varnish, and dirt can build-up and create a clogged carburetor. As this occurs, the carburetor may get too much air and not enough fuel. The result is known as "running lean" and the unfortunate symptom is a popping noise from your engine compartment. Cleaning with a trusted carb cleaner like CRC will quickly remove the deposits and eliminate the engine noise.

Is there black smoke coming from the exhaust pipe? When the carburetor gets too much fuel and not enough air, the result is known as "running rich." Get rid of the black smoke with a regular carburetor cleaning.

Is your engine flooding? A dirty carb system may have debris or dirt in the fuel bowl. When this dirt accumulates, it can block the valve that prevents gas from entering the carburetor. This leads to gas spilling out of the carburetor and onto the spark plugs. The result can be a flooded engine.

Finally, your car won't start. While there are several reasons why a vehicle turns over but won't start, a dirty carburetor may be the issue. When the air/fuel mixture that's needed to start the engine is blocked from the ignition system by build-up, the result may be a car that won't ignite. Using Clean-R-Carb™ as part of the general maintenance and upkeep of your vehicle can prevent and repair these issues, keeping your car moving and running clean.

CRC's Clean-R-Carb™ 50 State Formula is the carb cleaning solution for all your cars, trucks, tractors, lawn mowers, tool engines, and recreational vehicles.

Rely on CRC as a problem solver for clogged carburetors and as a preventative maintenance to keep the engine running smoothly.
