ROCHESTER 2GC & 2GV 2-Barrel: Overhaul: Notes
Carburetor cleaning and overhaul is generally the result of a customer complaint that cannot be remedied by external adjustments or parts replacement with the carburetor installed on the engine.
Flooding, stumble on acceleration and other performance complaints are, in many instances, caused by dirt, water or other foreign matter in the carburetor fuel bowl, jets or passages. To aid in diagnosing the cause of complaint, the carburetor should be carefully removed from the engine so as not to agitate or drain the fuel in the bowl. Contents of the fuel bowl may then be examined as the carburetor is disassembled.
When cleaning and overhauling a carburetor, identify the carburetor by the model number stamped on the main body, adjacent to the fuel inlet fitting. Using this number, always order and install a complete Repair Kit which contains the necessary parts and gaskets.
