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.

Works great, easy install

Hooked the power up to the stator post on the alternator, no issues even though I was only reading 7 volts there.

Master Tech

Game changer for older classics using vented heat tubes and other hot air choke warm up. Excellent item to make your classic much more user friendly. Easy install
