Rob,
Which hole are you talking about?
All the holes in the housing and in the throttle body seem to be clear.

The vacuum advance works but there is no vacuum to the advance. For some reason the port isn't working. I increased the timing and switched vacuum ports. Most of the hesitation is gone. Later today I'll unscrew the nipple to see if it's plugged.

Arlie,
I am talking about what you might call a "squirter" in a two or 4 barrel carb. The hole that the gas exits into the venturi. If you saw a small amount of gas entering the venturi when you open the throttle plates then it is most likely not plugged.

The vacuum port will not have any vacuum present at hot idle at 700 or so rpm. When you open the throttle it should then have vacuum present. The same as any Ford carb of that era. It is what the call "ported" vacuum that has no vacuum at hot idle and then comes in when you open the throttle.

There is no vacuum at idle or when I open the throttle.

Arlie.
Try to blow through the port. Sounds awful, but if you can put a nipple on it to blow with your mouth you can tell best. If it does not blow through then get out the carb cleaner and some compressed air.

We need vacuum at this port when the throttle plate opens. you may need to take the carb back off and turn it upside down. It is supported by a small slot or hole near the spot where the throttle butterfly closes against the throat of the carb. You can also fight a compressed air nozzle near this orifice to blow it out. It is not the orifice that the idle mixture screw is in.

{sigh}
The gasket covers the holes. It looks the kit maker didn’t understand or didn’t care that ‘68s differ from the previous years.

After thinking about that a little more I realized the gasket is correct

Upside down, inside out, backwards, something. Never trust former owners.

Arlie,
It was painful, but I think you FOUND IT!!!! I am always very careful in disassembly by chance it had the correct gasket and installed correctly. At the same time this assumes that the prior rebuilder did it correct…… Some carb kits cover many years and contain many versions of gaskets in them. Especially true when rebuilding a 2100 Autolite.

I bet the hesitation disappears after this!!!
