Help

Where does this go? Comes off of a port on the carb and was just hanging there. 1978 F100 300 6 cyl.

Spent over two hours trying to figure out where this goes to and I'm stumped.

I'm pretty sure that feeds the part of the choke that is hot air and goes to/through the exhaust manifold?

It looks like the short stub end that is supposed to go into a hole in the exhaust manifold, or other similar place that would pick up hot air, has broken off. Look around in the area where it dangles and see if you can find a small hole with a piece of tubing in it. That'll be the spot it goes to.

The line in your hand is the fresh air IN. Which connects to the bottom, hot air out the top feeds the "hot air choke".
Search " hot air choke" for more photos and repair info.
Or install a manual choke.
Good luck, Jim
