I am adjusting my carb now. In the factory manual it says to 
test the idle solenoid, turn on the key and touch the wire to 
the solenoid.  I get no audible click. What should the voltage 
going to the soleniod be ?  Is there any way of setting the idle 
without the soleniod working. The car idles @ around 1500 rpm. 
The carb is off the car right now and I am setting the automatic 
choke to spec's.
Now lets see, to make it to Carlisle I need to paint top frame, 
install top frame, install top, time the car, strip 3 more rims 
and get new tires. Sure it's possible.

: the solenoid.  I get no audible click. 

you should... and you should be able to hear it. The solenoid 
won't do a thing if the case isn't properly grounded 

(screwed into the carburettor; which is bolted onto the manifold; 
which is bolted onto the head; which is bolted to the crank case; 
which has a ground strap from it to the chassis)

:)

Touch the case of the solenoid to the intake manifold, then try 
testing it.

: What should the voltage going to the soleniod be?

12v

: Is there any way of setting the idle without the soleniod 
working. 

no. The idle solenoid acts as a valve that allows gas to the idle 
jet. If the valve isn't working properly, the carb will NOT draw 
gas from the idle jet.

: The car idles @ around 1500 rpm. 

that's probabally because it's running off of the main jets.

If the solenoid still appears "defective", take the plunger/valve 
out of the end of it and clean them thoroughly (actually, do this 
anyways) It might just be gummed up real bad. Low current 
solenoids like this rarely fail --- unless the plunger is stuck 
open. That's when they draw the most current (low inductance). 
That's when they fail.

...I have to admit, though --- I replaced mine anyways... but it 
was totally unnecessary... just did it with the carb rebuild for 
good measure.

      Bob, I just did this earlier today just to see what would 
happen. 
        Car was all warmed up and running smoothly, I unhooked 
the idle sol. and the car died.

        Also I did a quicky rebuild on the carb (lifted the lid 
carfully and cleaned and blew out jets and passages)and had no 
idea that the sol. came apart till it was apart on the bench, so 
I cleaned and blew it out too.
             The carb seems to work better now.   Idles at 800 
rpm and haven't adjusted the idle setting.

If the original lead to the solenoid is bad can I piggyback off 
of another 12 Volt lead. Are there any relays I need to worry 
about does the solenoid do all the work.
Thanks Again

Just find out what the deal is with the solenoid ctrl wire. It's 
a switched +12 through the ignition. 

...It would be OK to run a jumper from the switched + lead on the 
ignition coil to the solenoid.

Measure for voltage at the [disconnected] lead when the key is in 
the on position. If you don't get +12, find the problem (bad 
connectors/etc)

After verifying proper voltage, hold the meter probe on the 
connector, touch it to the [properly grounded] solenoid 
connector. You should see an instantaneous drop in voltage if the 
solenoid is trying to do it's job.
