How can I tell if my carburetor has been modified with a one-piece venturi?
The carburetor data tag provides valuable information. There are four additional designations normally stamped on the data tag. A “V” stamp indicates a one-piece venturi is installed. A “MF” stamp indicates a metal float is installed. A “92” indicates the recall on metal floats that occurred in 1992 has been complied with. An “A1” designation indicates the drain plug has been removed and inspected for excessive thread lubricant and the carburetor bowl has been flushed.
