cold engine acceleration problems revisited

["Walter" <Whalt@xxxx>]

Okay, I've read up on the 'acceleration enrichment circuit', and it makes
sense that my problem could be in this circuit. But it will probably be
several days before I can really get into it. I suppose that in order to
trouble-shoot this circuit that I am going to need to get a T-adapter for my
vacuum gauge. It looks like my problem could be:

1) a bad thermal vacuum control valve
2) a bad delay valve
or
3) a bad control pressure regulator (again).
or
4) a clogged or leaking vacuum hose in this system.

I'll keep you posted on my progress. In the mean time, do y'all have any
suggestions?

Believe it or not, I actually had a clog in a vacuum hose on a GM car. I
couldn't believe it. I had to cut the hose open to see what it was. What I
found looked like the end of a plastic golf ball 'T' that may have broken
off inside while someone plugged the end of the hose to do a diagnostic.
