[DeTomaso] Carb question

[SOBill at aol.com]

The original Ford Autolite carburetor installation included a  throttle 
solenoid which was used if the engine got too warm while  idling.
 
This a simple solenoid, mounted on a bracket, with a plunger  which changes 
the throttle stop position when activated. The activation could be  
connected to the AC compressor clutch wire to up the throttle position when the  
compressor kicks in.
 
Holley makes a "fast idle" solenoid:

various mounting brackets.
 
 
Have fun  today,

I have a  408 stroker with a Holley 750.  When I try to set the idle, I 
seem to  have only two choices.  1) set the idle too fast (1800 rpms) so that 
when  I turn on the air conditioner, the car won't die (it goes to about 1100 
rpms  with the a/c on), or 2) set the idle for 1100 without the a/c, but 
when I turn  on the a/c it drops down to about 500 rpms and is at risk of 
dying when I let  out the clutch.

I've tried adjusting the idle screw on the carb in  minuscule increments, 
but no luck getting better  results.

Suggestions?

Thanks,

Chris
