Correct.
I removed the coolant temp. sensor that's located at the forward end of the
intake manifold. In it's place, I inserted a 155° 3-way CTO switch and
connected ported and manifold vacuum hoses to the switch; the third connection
going to the distributor.
After I had done the nutter, it just wouldn't idle nicely when cold using
ported vacuum (essensially 0" at idle). Runs like a champ now.
BTW, I like the solenoid idea. I was thinking of doing that for winching
operations.

I was playing with the sol-vac and the new switch today and found I
can get it to idle anywhere from 900 to 1400 rpm, I just achieve the
idle point I want and then flick on the switch. From what I have read
the sol-vac doesn't have enough power to open the throttle but it can
hold it where ever you set it....... now I have to quit playing with
it at stop lights :). I also wired my carb/intake manifold heater to
the same switch bank and on the really cold days I can flick it on for
a few minutes and get the vapors in the intake nice and warm before
starting it. I'm not sure where you live but it can get to -40 Deg C
here in Alberta and my vehicle sits out in the open when I'm at work
for up to 13 hours, it's my version of a glow plug.
Thanks for the info I might consider trying the cto thing out when I
get a chance.

That's neat, never though of that for a 'hand throttle'. I will pass
that on to others for sure. I even have my old one kicking around and
likely will put it back on.
That would be a great thing to have when the idle tubes plug up and it
won't idle for crap but runs good over 1200 rpm or for winching.
I got a manual choke kit from Canadian Tire and put it in mine. That
way I can drive away in the real cold without having to 3 foot drive the
thing until it warms up. The electric choke is just a plain timer that
goes off according to how long it has had 12 volts, no matter the real
temp.
I can set a fast idle by pulling on the choke when I have the pedal down
where I want it, then letting off the pedal and pushing the choke back
in. It stays on the fast idle cam until I blip the gas pedal.

That's neat, never though of that for a 'hand throttle'. I will pass
that on to others for sure. I even have my old one kicking around and
likely will put it back on.
That would be a great thing to have when the idle tubes plug up and it
won't idle for crap but runs good over 1200 rpm or for winching.
I got a manual choke kit from Canadian Tire and put it in mine. That
way I can drive away in the real cold without having to 3 foot drive the
thing until it warms up. The electric choke is just a plain timer that
goes off according to how long it has had 12 volts, no matter the real
temp.
I can set a fast idle by pulling on the choke when I have the pedal down
where I want it, then letting off the pedal and pushing the choke back
in. It stays on the fast idle cam until I blip the gas pedal.

Yes the choke coming off so quick is a major down fall, it might work
in the States but with the weather here it just opens up way to quick.
I have also read somewhere that someone put a reostat on his choke so
that he can vary the opening, I thought to myself there is a guy who
is thinking.
I looked at the sol-vac not as a useless piece of junk under the hood
but as an opportunity. :)
