NOTE: If this manual is not fully understood, installation should not be attempted. Failure to follow these instructions, including the pictures may result in subsequent system failure.
REMOVAL:
Identify, label, and disconnect the vacuum lines to the air cleaner. Labeling these connections will help ensure that they will be properly re-assembled to the air cleaner after the installation of your Holley carburetor.
INSTALLATION:
A few GM applications with air conditioning use an idle step-up solenoid to increase idle speed during compressor operation. If possible, remove the solenoid and its retaining nut. If the solenoid is permanently fixed to the original carburetor, you may want to purchase GM parts 1997416 solenoid and 7042654 nut and install them on your new Holley carburetor, using the appropriate bracket. Take the short ground lead from the unassembled parts and connect the bayonet end to the proper terminal on the Holley electric choke cap. See Figure 1.
