FINISH INSTALLATION
1.

Re-connect throttle linkage, wires, hoses, etc. Your

Edelbrock carburetor may have more vacuum outlets

than the original. Leave the caps on those outlets

which won't be used. It is also required for proper

operation that you bypass the vacuum amplifier and

vacuum reservoir as seen in figure 3 & 4 . The

throttle positioner may also be removed on some

applications.

2.

Re-connect the air cleaner being careful not to over-

tighten the mounting nut which could damage the

carburetor. Install a new air filter (if needed) and re-

connect all hoses.

3.

IMPORTANT NOTE: With engine off make sure

that there is no interference when opening and

closing the throttle. Be sure that there is no binding

or hanging up between idle and wide open throttle

as this could cause the throttle to stick, resulting in

loss of engine speed control.

4.

Re-connect the negative battery cable to the battery.

SMOG INFORMATION
Regarding the 1905 carburetor that is installed on your Chrysler engine. The original thermoquad carburetor relied on

the vacuum amplifier to operate the EGR Valve. Using the new Edelbrock carburetor, the vacuum amplifier is not needed.

The EGR can be rerouted using the (port “D”) ported vacuum port. The throttle positioner may also be removed since it

is not applicable to the new carburetor. This was how Edelbrock tested the vehicle when they were granted the VC27156

exemption.
