Re: No Ported Vacuum
One possibility is that the carburetor was rebuilt, and somebody used the
wrong gasket. I have seen carburetor rebuild kits, with two or three
gaskets for the same job. If you pick the wrong one, then something winds
up not connected, or connected wrong. This would explain your port being
open, but no vacuum.

Re: No Ported Vacuum
Hi Earle,
And I remember rebuilding a little Vega carburetor and there was no
way to make the accelerator pump work without punching another hole it
the float gasket. Which was the initial problem she bought it with.

Re: No Ported Vacuum
When I took auto shop back-in-the-day the instructor drummed it into us to
be careful with carb gaskets as they would often seem to fit perfectly
upside down and that replacements did not always have to correct holes and
we were to line the new and old gaskets up and compare them.
This won't help in this case unless he was to get a card kit and rebuilt it
himself now.
Other than a gasket or clog somewhere I am at a loss to figure where the
problem unless he has 2 hoses crossed which used to be quite possible.
There used to be a number of similar sized vacuum hoses under the hood.

be careful with carb gaskets as they would often seem to fit perfectly
upside down and that replacements did not always have to correct holes and
we were to line the new and old gaskets up and compare them.
This won't help in this case unless he was to get a card kit and rebuilt it
himself now.
Other than a gasket or clog somewhere I am at a loss to figure where the
problem unless he has 2 hoses crossed which used to be quite possible.
There used to be a number of similar sized vacuum hoses under the hood.

Re: No Ported Vacuum
Another couple thoughts.... has the OP checked to see that the hose is not
leaking or hasn't collapsed midway along the length?
When you spray cleaner into the port.... does the engine sputter or stall?
