Where does the vacuum line go that comes off the rear of the passenger side exhaust manifold. I am not refering to the choke tube. This comes off the back and has vacuum pressure. it would be nice if I could post a picture but the file is too big.
The choke hot air tube has vacuum from the carb. That’s how the heated air gets pulled past the choke coil. The other end of that stove in the exhaust manifold is obviously also going to have vacuum, since air has to be pulled into the stove to be heated before it goes to the choke coil. It’s all the same tube.
Joe you’re right, the carb choke of that type pulls vacuum. Your description is correct.
However, the exhaust manifold isn’t pulling or have vacuum, the carb is pulling vacuum. The exhaust manifold tube simply provides heated air for the carb vacuum.

I thought that’s what I said. The tube in the hot air stove simply passes through the manifold casting. One end connects to the carb and sees manifold vacuum. The other end is the inlet for that vacuum source. I never said the exhaust manifold was producing vacuum.
