I'm having a hard time finding the replacement part number for the electric choke on my 4-barrel Rochester carb. 1988 3.7LX. Anyone have this info handy?

Ayuh,..... Welcome Aboard,....... What's it got now for the choke,..??

The electric element for a rochester should be a dime a dozen, most anywhere ya look,.....

There are a few options for the Rochester, just trying to find the right part # without removing from the carb first.

So we really do not know if it is really the original carburetor for that year ? How do we determine what model that carburetor is with out some identification numbers ?

It is the original carburetor. I cannot seem to find a part number for the electric choke replacement in the online catalogs.

Take a picture of the carb, record the serial number on the carb, go to your local parts store and show them what you have and need. It’s just an automotive choke system installed on a marine carb. They should be able to fix you up. If not retry a different parts store.
that being said, are you getting power to the wire that goes to it? Of not it won’t work.and they are adjustable.
