Steve,
Oh, that's my fault for not looking at the actual solenoid before
writing my post. So the top port goes to the manifold and the
horizontal port goes to the distribuotor? I guess that's what i need to
know.
Thanks so much!

My TCSA has 2 ports 1 vertical and the other horizontal pointing toward
the
front. The horizontal port is vented out the bottom of the solenoid
when not
actuated and connects to the distributor. The top port is connected to
manifold vacuum. What was happening was that, when the lines were
reversed,
vacuum would build in the advance line and not vent, keeping the spark
advanced and idle high. The other line would have been a vacuum leak,
but
the "natural richness" inherent in the ZS carb masked any lean running
problems. When I corrected the lines, the idle did drop about 50 rpm
and
doesn't bump up to 1200 after running in 4th and coming to idle.

Subject: Re: TCSA & Vacuum advance woes
Now I'm a little confused...I thought the solenoid was either open
(in 4th
gear) or closed. How does hooking up the vacuum lines reversed change
its
operation? In any case, I'm planning on reconnecting the lines to my
solenoid (disconnected by a PO) again and I'm now wondering which way
round
it should be connected? Does the port pointing at the manifold connect
to
the manifold and the port pointing at the distributor connect to the
vacuum
advance? That seems the logical choice. Or...should I bypass the
solenoid
completely and just go directly to the distributor?
Any advice appreciated!
thanks,
