INSTALLATION
A. PREPARATION
Before installing a carburetor, look it over carefully for signs of damage accidentally incurred by improper storage or mishandling.
nuts must be drawn down tight to prevent leakage between the carburetor and manifold. Connect the distributor vacuum lines, the fuel line, throttle and choke linkages, making sure there are no worn or loose connections.
B. INSTALLATION
Be sure the carburetor mating surface of the intake manifold is clean. Then, using a new flange gasket, secure the carburetor to the intake manifold with the four mounting nuts and lockwashers. Tighten the mounting nuts alternately, a little at a time, to evenly compress the flange gasket. The
It is recommended that all connecting lines be threaded to their respective locations before tightening the carburetor to the manifold. Final tightening of lines should be completed after tightening carburetor to manifold.
