Aftermarket & OEM Carburetor

A clogged carburetor is a common problem for older vehicles. This intake component is the place the air and the fuel components are joined together in the correct ratio before heading into the intake manifold. When the carburetor is clogged, the engine will sputter when it is running and the idle will be rough. If this intake component has a piece of dirt in the needle and seat, excessive fuel will be leaking into the system that could cause the engine to diesel when it is turned off along with making the mixture extremely rich. In extreme instances, the clogged carb will not permit the engine to start or run.

The carburetor is on top of the engine mounted to the intake manifold. It is made out of aluminum with steel screws. The jets and slides on its interior are made from brass so when they are screwed into place they will be held firmly without any locking mechanism. The air and fuel are mixed in the central chamber of the carburetor. The fuel has to be filtered then flow into the bowl where the float, needle and seat are located that open when the demand for fuel is made by the position of the throttle. This is the location dirt interferes with the flow of fuel the most.

The replacement procedure for the carburetor requires that the fuel line be disconnected first then the throttle linkage. There will also be numerous vacuum lines connected to the carburetor that will have to be disconnected. Many technicians place a tag on the lines and its position on the carb so the new intake component can be correctly reattached once the overhaul or replacement of the component is completed.
