AVS Rebuilder

Well i just got off the phone with carbjunkys and wasnt real impressed. I asked if they would have a solenoid for a 70 avs and the answer was "no". The second comment was "you dont need it" and the third was " it was only used on air conditioning cars to raise the idle". So now the question is what 70 avs carbs had it and why. The carb i have clearly had the solenoid mounted on it.
