Rochester 2 & 4 barrel electric choke conversion kit.

Electric choke conversion kit. Use this to convert your hot air, or divorced choke into an electric choke, eliminating replacing manifolds, or stove pipes. With the exception of divorced choke type, you will need your choke housing in place. This kit does not convert manual chokes.

SPECS:
  • Thermostat is twisted clockwise to close choke valve.
  • Cap diameter = 2.25"
Electric Choke Instruction Sheet
Includes instructions.
Remove your stove pipe.

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.

R2 - Rochester 2 barrel
R4 - Rochester 4 barrel

APPLICATIONS:
You must match your carburetor number to get the correct part.
