Turn off the engine, and locate the carburetor. Partially loosen the bottom nut, and let the gas drain out. Put the nut in a cleaning solution. Take digital photos of each step, and upload them to a computer.Continue Reading
Use the pictorial guide to help answer any questions during reassembly. Alternatively, sketch the procedure, and label the parts. Both procedures can show you where the parts go. Mark the vacuum lines with masking tape, and label each piece. Block the throat of the carburetor to avoid losing small parts, which requires removing the manifold to search for anything you drop.
As screws and bolts may differ in size, insert each one back into the base so that they are in the correct spots when it is time to reassemble the unit. Use a flared nut wrench to remove the fuel line. Upon lifting out the carburetor, block the opening of the manifold with a towel to protect it from foreign objects.
When you remove the gasket from the manifold, use it to match it with the new gasket, as gaskets often have subtle differences. Clean the gasket area on the manifold carefully. Clean the carburetor, and then return it by reversing the steps used to remove it.Learn more about Vehicles
