Installation of Dual Carburetors
- Steps:
- The first step in the carburetor installation is to place the two throttle shafts side-by-side and lock them together. This orientation is critical since it allows the throttle shafts to open in unison during acceleration.
- The two carburetors are positioned onto the mounting studs and fastened with nuts.
- The nuts are tightened carefully using an open-end or box wrench. Needle-nosed pliers are also helpful in this process as they help in installing the nuts on some of the hard-to-reach studs.
- With the carburetors mounted, the throttle linkage is connected and checked for proper spring-back and operation.
- Next, air-cleaners and covers are installed. These are foam-style cleaners are covered by a chrome cage.
- The covers are held in position by wire retainer-clips. The clips make it easy to remove the air cleaners later for cleaning or replacement.
- With the covers installed, the fuel line is installed between the first and second carburetor.
- Next, the final fuel line is attached to the rear carburetor. This line drops back behind the engine, and connects at its other end to the original fuel line coming up from the fuel tank.
- With the lines installed, they are fastened securely with hose clamps.
- The installed carburetors are then adjusted to synchronize the throttle shafts. It's critical that both two-barrel carburetors, and the individual throttle plates, open simultaneously to optimize fuel-flow through the carburetors. This ensures that all cylinders receive the same fuel-air mix to help the engine run properly. With this new carburetor system, the Alfa's engine can run on unleaded premium gasoline, and can be custom-tuned to optimize performance using that type of fuel.
- In the segment that follows, a new exhaust system is installed on the Alfa.
