What is it?

I just took delivery of a 78 SC. On the left side of the E-brake handle is a leaver with a black knob. The owners manual has nothing about this. What is it?

Not that familiar with SC's, but that is the traditional location for the hand throttle to adjust idle speed in cold weather.

The only levers next to my ebrake are the heater "on-off" levers. The manuel shows a Hand throttle control knob (Black knob) to the left of the e-brake for 75 and before. Dn't know what its doing on a 78SC

I suspect you do have the heater flapper box cable lever there but someone changed the knob (due to wear and tear) to the old black choke knob. (I've bought more than one P-car where the PO "restored" badly --- especially when it has been done by a "refurbish" shop. )

Have someone move the lever while you get under the car (engine doesn't need to be on) and look where the exhaust heat exchangers link to the body (this is the flapper box is) via a soft (paper/foil/rubber/neoprene/whatever-they-used) 2-3 inch tube--- if you see movement then that's what it is.

Thanks to all. This is a chrome lever on the left side of the E-brake handle with a black knob. It don't seem to do anything. Only moves about 2", no change in heat , idle nothing.

Seems to me it is the hand throttle. It should have a plastic link inside the tunnel which pushes against a stop on the throttle cable. I can't remember the number but I believe you can buy the plastic link from Pelican. I just replaced mine as the old one had disentigrated over the years.

Makes for a reasonable cruise control on older cars.

I'm not sure but I thought that all cars past 1975 which had a CIS installed do not have the idle control lever. I was under the impression that the CIS engine uses the warm-up regulator for this. This would lead me to believe that it is a heater control level with the wrong knob installed. You should be able to see the flapper valves close under the car when the lever is pulled. The flapper valves are located behind the heat exchangers. Follow the flexible air ducts that run off the back side of the heater boxes to find the flapper valve. There should be some tension on the lever. If there is not, the cable that runs from the lever to the flapper control valve my be broken. The flapper valves are spring loaded to return to a no heat position (the flapper valve is open and dumping hot air towards the ground).

End the madness! The SC NEVER came with a hand throttle, that was long gone by '78.

(that being said, who knows what someone may have done to the car in the past 20 or so years!)

Mine also has it (911-69-S) and also donīt know what is it for....

Have a '76 CIS basically.
Hand throttle lever is there, and the owners manual describes it-not mentioning when to use.
When I bought the car, no cable was attached and still isn't.
Can anyone confirm if I SHOULD have it attached, and, if so, where does it go?

The black knob on the left side of the e-brake on your '69 is the hand throttle control. Mine broke a few years ago and I fixed it immediately. Life is unbearable in an early car without a hand throttle.

On my 75 CIS, I have that knob and its the hand throttle, very usefull on cold starts.

Is it possible that your hand brake assembly has been replaced with one that is older? It is true that SCs do not have hand throttles, but some earlier CIS cars may have had them. I have seen one but do not know if the handle was stock. Stranger things have happened to these 20 year old cars.

I have tracked down the P.O.'s phone #. I will try to contact him in the next week or so. Then perhaps I can end this mystery.

You ARE sure this is really an SC, right????

What else could it be? Date of manufacture on door jam is 09/77.

My car is a 78 SC manufactured in late 77 and it has a functioning hand throttle. Morever,the hand throttle is described in the 1978 owner's manual so it cannot be a later conversion. What i suspect is that it was used at the initial stages of the SC production and abandoned later.

Opposite from Jen's '76 CIS, my '76 CIS does NOT have a hand throttle. The owner's manual describes it, but I have none. Maybe the PO took it out?
