GENERAL:

This kit is designed to fit a range of applications. Extra parts are provided to facilitate the general conversion. All parts may not be

Due to emission requirements, the number of vacuum lines and tubes is increasing. It is advisable when disconnecting tubes and

lines, to identify them in some manner so as to avoid confusion later. Trace the lines back from the carburetor to the individual

components, and identify that line. In the event that any components are unfamiliar, use a numbering system which corresponds to

each line and its original component.
