How To Use Carburetor Cleaners To Clean A Small Engine

Remove the Carburetor from the Engine

Kick off the exercise by removing the carburetor from the engine. Before this, turn off the fuel valve that exists on the fuel tank. Follow this by loosening the screws which hold the clamps together at the front and the back of the carburetor. Lastly, carefully yet steadily get the carb out of the engine. Take great care that you do injure not yourself.

Get rid of the float bowl

You now have to get rid of the float. This is the bottom part of your carburetor. To do so, unscrew the four screws which bind it to the carburetor. These screws do strip easily. You hence have to exercise some great care and caution as you remove them. Pull the float bowl steadily thereafter. You might require a pair of needle-nose pliers to accomplish this. 

Dismantle the jets

Dismantle the jets

Jets refer to those screws which contain some holes in their centers. It is through these holes that the fuels flow in order to mix with the air. The exact procedure to use varies from one carburetor to another. Use a screwdriver and some set of pliers to unscrew the jets from the carb. It is necessary that you pay attention to your manufacturer’s specifications as you go about this business.

Remove the outer portions of the carburetor

Conclude the dismantling process by removing the outer portions of the carburetor. This process requires the use of a flathead screwdriver. As you remove these screws, be slow and cautious to avoid the unlikely possibility of damaging the remaining parts.

Clean the Parts

You have now got to the core of the matter. Soak the constituent parts in a gallon of carburetor cleaner solvent for 1 hour or so. At the end of this duration, scrub those parts using a wire brush after which you are to spray them using the choke cleaner.

Clean the Parts

Do the same to the holes from which the choke, float needles, idle screws, and jets came from. Hold the jets through the light to ascertain whether the parts are indeed spick and spun. You may consider blowing some compressed air through the holes to clear any residual debris.

Conclude this step by placing the carburetor out in the open to dry completely. If there is insufficient sunlight outside, the compressed air will definitely come in handy.

Reassemble the parts

Having concluded cleaning the parts, the time has now come to reassemble them. This is a very delicate process indeed. That is because there is the risk of mismatching the various parts and components. Then, different makes and models of carbs feature varying parts and installation procedures.

You will have to rely extensively on the manufacturer’s manual to go about this issue. As a general rule, you have to start with the O-rings, then the gaskets, through to the jets, outer parts, and finally the float bowls. This is the best time to replace any parts that are completely worn out.

Return the Carburetor

You should now return the carburetor to the throttle cable. Place the throttle cable at the top of the carb and attach the spring. Then, place the needle in the slide and fasten it by compressing the spring and the hook on the end of the cable.

Next, slide and thereafter wiggle the carburetor back to the rubber boots. Finish off by tightening the screws on the clamps in order that they might hold the carburetor firmly in place. After you are through, fix the fuel and the overflow line back to the carburetor.
