I believe that is an electric cranking signal valve, as it goes to the cranking signal port on the plenum and no other cranking signal is present (that I can see..)

Thank you for your ID

It was soooo hot yesterday that my head swelled and I though for a moment I knew something about Rochester. How did I do on the L-88 hood?

I have a survivor 61 FI unit that hasn't been touched in 35 years. It has a similar hookup. Was this done by the factory or was it creative engineering? Jerry

Re: 1961 FI Survivor Photos

Whose factory? Not Rochester or Chevrolet. An aftermarket idea that apparently either had some merit or an outspoken advocate.

Re: 1961 FI Survivor Photos

A Popular Hotrodding magazine article form the 70's, titled, "All About Rochester Fuel Injection" shows a photo of a modified 61 injector using a turbohydromatic solenoid switch. The article goes on to explain it is used to replace the cranking sigal valve which commonly failed. "The CSV aparrently often did not seat correctly. As a result, the signal to the cold enrichment system, which should shut off when the engine starts, was maintained and caused an over rich condition. The turbo h-m switch is placed between the CSV and cold enrichment housing. It is wired to the 'start' pole of the ignition switch".

I met a guy from West Windsor, NJ some years back and he related an article he wrote regarding the use of the turbo trans switch on the early FI units. Don't recall the publication, perhaps the Restorer. Common solution to a common problem still applicale today.
