What is the piece called that...

[morgan95]

What is the piece called that screws into the engine body (I think) and attaches to (some part of the carburetor) I believe it moves when the throttle bar moves. I apologize I don't know how to describe it any better than that.

Choke? Don't quite fully understand your description.

[Corvair.crazy]

Maybe the throttle plate..

Are we talking about the missing throttle rod like you were asking about in your other thread?

Do you have a photo where we can look at the area you are asking about?

It would help when you start a new thread to remind people what year Corvair you have so we can give better answers. I would suggest that you add the information to your signature line so everyone sees it automatically each time you post.

My corvair is a 1963 monza

The first three pictures are of the right carb and it has the cable/linkage or whatever it is.

And the last 2 photos are of the left carb and the missing cable or linkage and where it attaches to the carb and where it attaches to the engine frame (I think that's what it would be called)

Sorry if this still doesn't clarify things I don't know the technical terms.

That is a choke rod. One is missing. there is a bi-metallic choke coil mounted under the head that the rods attach to.

Look inside the lower shroud (engine not running!)(engine NOT warm either)
with a good flashlight to make choke coil is still there. If you look down the
hole for the choke rod, you should see female threads off the choke coil.
If the choke coil has been removed, you'll end up removing the lower shroud
to replace it, otherwise there's nothing for choke rod to attach to.

Here's a pic of the missing rod joined to a choke coil that is attached underneath as mentioned. Top sample is EM and bottom is LM.

[morgan95]

The choke coil screws into the choke rod and the choke rod attaches to the car?

And if I'm not mistaken one end of the choke coil is threaded for the choke rod to screw into?

Did I get those two correct?

The choke coil has a straight rod attached that extends up into the head. This is normally one assembly when purchased. The straight rod has a threaded coupler fixed to it that is permanently attached. The angled choke rod that is in the engine compartment, threads into the coupler and has enough threads that you can adjust the final length to get the choke set correctly .

Yes, the choke rod from the carburetor is threaded into the rod that extends upward from the coil on the underside of the cylinder head. To clarify...

This is a view of the underside of the cylinder head, near the exhaust ports. The picture shows the mounting location where the choke coil is riveted to the aluminum head. A loose rivet is shown next to the rivet hole. When attached to the head, the metal coil responds to increasing cylinder head heat. It starts out when cold by applying spring pressure to the choke mechanism on the carburetor, forcing it into a closed position. As the engine heats, the coil contracts and gradually releases spring pressure on the automatic choke mechanism. When the engine is at full normal operating temperature the spring pressure is minimized, which allows the carburetor choke mechanism to move to the full open position.

Alright that clarified thing's thank you.

Is a choke thermostat necessary or is it more of a luxury so to speak? In other words do i need it like I need the rod to get my car to work properly?

You need the choke rod and choke coil to work together. One without the other is useless. Until you can get it fixed just be sure the choke plate stays open and you'll have to deal with the hard starting and drivability issues until the engine is warm. Once the engine has warmed up and the choke plates are full open they serve no purpose (until the next cold start).

Read here too for good info about choke functions and why they are used.

I knew I need the rod and coil I wasn't sure though if I needed the thermostat.

Alright so this is what I need right? http://www.californiacorvairparts.com/p ... roduct=449

I'll give the link a good read over.
