I have a 66 coupe 289 2V. There is a valve of some type midway between the PCV valve on the valve cover and the carburetor. It is attached to the OCV hose. There are no cables attached to control movement of the handle. Can someone please tell me what this is, what it's for, and what position it should be in. I assume the handle denotes the position of the valve.

Thanks
John

I have a 66 289 2V with California smog . My PCV hose doesn't have anything on it. Soulds like some aftermarket item to me.

I rec'd this in a PM from a member on Fomoco.com. A search on the forum provided some more info. Seems like it only came with factory air on cars delivered to warmer climates. It was not always installed on cars with dealer installed AC.

Its a 'hot idle compensator' valve, used mainly on cars with
A/C. It was designed top provide a smoother, 'cleaner' idle
condition and will be found on lots of cars in CA due to their
more stringent emissions standard.

Thanks mipack for the help and picture posting.
