HOW TO REPAIR THE CARBURETOR(WITH VIDEO)

 

What is the Carburetor?

Before fuel injection systems became rampant, the air/fuel mixture was controlled by a carburetor. The carburetor is placed on the top of the intake manifold, and has both air and fuel inlets. The air inlet is sometimes a duct attached to the carburetor or can be just an air filter housing mounted directly on top of the carburetor. The fuel is given by a fuel line coming from the fuel tank. The carburetor is responsible for atomizing fuel and spraying it into the air that enters the intake manifold. There are two adjustment screws on a carburetor that control the idle speed and the fuel mixture when running. When the carburetor can no longer be adjusted to make the engine run smoothly, it may be time to change the carburetor.

Bear in mind:

  • A performance carburetor can be mounted to increase power, or a fuel-efficient carburetor can be installed to save on running costs.

How it’s done:

  • The battery is disconnected and the air filter is taken out
  • The carburetor is removed and the new carburetor is mounted
  • The new fuel filter is installed and carburetor is inspected for leaks and adjustments
  • The battery is connected and the air filter is mounted
  • The car is road tested for proper operation

Our recommendation:

Have the carburetor adjusted at every maintenance interval. If the carburetor will not adjust properly, replace it with a high quality part. The labor cost to rebuild a carburetor is prohibitive and often is more expensive than installing a new oet.

What common symptoms show you may need to replace the Carburetor?

  • Engine runs rough and stalls
  • Engine will not start
  • Engine leaks or smells like raw fuel
  • Backfiring or popping through the exhaust

How important is this Repairs?

Without a properly operating carburetor, it can be extremely hard to keep the engine running reliably. This can lead to dangerous situations when driving or costly tows if the engine stalls.
