Valve in my Intake Manifold?

[caoverton]

Hi, I am new to this stuff. Just bought a 1951 B3b. I am learning about this thing slowly, but found something I couldn't figure out.

There is a valve of some sort in my front intake manifold. The valve is spring loaded, and there is a lever on it that looks like it might be moved with a cable of some sort.

It is not the heat riser, 'cause it is just below it on the exhaust manifold.

I don't have a clue.

Welcome!

Pictures would be good. And, of course, pics of the truck!

would it be part of a wolf whistle?

Are you sure it is the intake manifold? Perhaps an automatic choke temp sensor connected to the exhaust manifold.

it scares elephants off the highway..bet you have not had any trouble with elephants..

quick pic would get a concise answer I woud think..it could be anything

here are some pics of the Valve. It is on a T306 engine (218 cc)

And One of the Truck.

The valve is your automatic choke also known as a Sisson choke. There is supposed to be a rod from the lever to the choke on the carb. It appears part of it is missing, there should be an electric solenoid on top.

You might make a note of the position of the lever. See if it changes position, cold to hot. If so it may still be working. Many were disconnected and replaced by a hand choke when they stopped working.

Up = closed

Down = open

It is up in the picture as if the motor is cold. If it goes down to a horizontal position when hot, it is working.

here I was hoping it was for NOS!

Thanks.

currently the choke will only half close, as the vacuum assist line to the distributor is preventing it from closing all the way.

I just saw this the other day, and like I said I am totally new to these old vehicles.

Is there harm in leaving it, or not replacing the solenoid, or the levee to the carb?

T306 is a truck engine, but the trucks didn't use the automatic chokes that the cars used. It appears that you have a car manifold on your truck engine. You should have a manual choke with a cable in the dash, next to the throttle cable.

The valve is your automatic choke .

I thought I already said that:cool:

I was way off..I put too much faith in them knowing what an actual valve was and maybe just could not guess the use..
