Due to technical reasons, electric choke kits are matched using the engine application. It is assumed that the carburetor, intake manifold and engine are original to the vehicle.
Examples of miss match:
Carburetor has been switched out.
The carburetor has been re-manufactured.
A performance intake manifold has been installed. This is OK if the manifold is a direct replacement.
Spacers have been added to the carburetor base - Divorced chokes only.
