How To Rebuild a Carburetor

Carburetors are integral parts on naturally-aspirated engines. One can find these in cars, motorcycles or even motorized equipment like lawnmowers. Carburetors are prone to break down due to wear and tear. Down the road, you might be faced with the task of having to rebuild and repair your carburetor. Even if carburetors of different engines might look different, the general steps for cleaning it up and rebuilding it.

For this task, you would need a carburetor kid, protective mask, safety glasses, carburetor cleaner and an old tooth brush.

  1. The first thing you have to do is to get a compatible carburetor kit from the dealer. These kits will usually have all the parts you’ll need to fix and repair your carburetor.
  2. Ensure your work space has good ventilation. Working on a carburetor typically produces a lot of fumes, which are very hazardous to your health. This is where the use of vapor mask comes in. Safety glasses will likewise protect your eyes from flying debris, grease and dirt. Good lighting is also critical since you will be working with quite a number of screws and tiny pieces.
  3. Study the diagram that comes with your carburetor kit. Again, carburetors from different vehicles, makers and models will look different. It would not be surprising that carburetors that are meant for cars and motorcycles as significantly more complex than models that are meant for lawn mowers. Pay attention to the details of the drawings. This will be handy when you’re putting the carburetor back together.
  4. Start by disconnecting the accelerator pump and removing the cover. The linkages along the choke itself should be removed as well. Be careful and take note how the links fit together. If it helps you, you may write the configuration of the linkages to make it easier for you to remember once you need to put it back together. Each hose and screw will have to be replaced so you also have to take note of these details.
  5. With the use of a brush and carburetor spray, clean each individual part. You may use a wire brush, but wires can damage the sensitive parts if you rub too hard. Toothbrushes would be a good option for this step.
  6. Put your familiarity of the diagram to use. Using the kit diagram and your earlier drawings for the linkages, put together the rest of the carburetor. Make sure that you tighten each screw carefully. Be mindful though that tightening the screws too much can strip the treads. Check each individual part on the diagram and make sure that they attached to the carburetor. Repeating the steps in reverse order will make you more likely to make all the necessary connections.

If these instructions have overwhelmed you, you can always opt to have a professional do this task for you. Just be ready to pay a premium for the service. But if you feel capable enough, then with a little time, patience and elbow grease, you would be able to do the job well.
