If you are experiencing issues with your ATV, Go Kart, dirt bike, moped, motor scooter or motorcycle and it's bogging down and dying when you give it throttle, the problem may lie with a clogged or dirty carburetor. A carburetor is responsible for mixing air and fuel in the correct ratio to ensure smooth engine operation. Over time, dirt, debris, and varnish can accumulate in the carburetor, obstructing the fuel flow and causing engine stalling. In this article, we will guide you on how to clean your carburetor the fastest and most affordable way by blowing it out with an air gun from an air compressor.

Before you start, make sure you have the necessary tools and safety equipment. You will need an air compressor with an air gun attachment, protective goggles, and gloves. Follow these steps to clean your carburetor:

  1. Locate the carburetor on your machine. It is usually found near the engine and has a fuel line connected to it.
  2. Start by shutting off the machine
  3. Next, disconnect the fuel line from the carburetor. Be cautious as there may be some fuel spillage.
  4. Once the fuel line is disconnected, locate the float bowl on the bottom of the carburetor. This is where the fuel is stored.
  5. Use a wrench/screwdriver to loosen the screws or bolts to allow the float to empty gas out of it to the ground.
  6. by blowing compressed air up through the drain line, it will be able to pass through and access jets and passages. These are the areas where dirt and debris accumulate.
  7. Using an air gun attachment connected to an air compressor, blow compressed air iup through the drain line. Make sure to apply 90 to 100 psi air pressure and blow for about 10 seconds. It helps to have someone twist the throttle a couple of times as your doing this to lift the needle valve up and out of its seated position. 
  8. Once you have finished blowing out the carburetor, tighten the drain set screw on the float bowl and Reconnect the fuel line.
  9. Start your machine back up, it may not want to start right away. Test it by giving it throttle and see if the issue persists. Your machine should now run smoothly without bogging down or stalling and if it is still having issues you may actually have to clean the carburetor, replace it, or take it in to a Professional scooter repair shop
