Dashpot adjustment for Rochester 2gc

[Hotrodjohn71]

Does anyone happen to have a 1965 shop manual that can share the vacuum dashpot adjustment for our Rochester 2GC carburetor? I've searched online but cannot seem to find an instruction sheet pertaining to our particular Rochester.

Ours only has one idle speed screw, (on the driver's side). The tech sheets that I find show a high-speed idle screw which ours does not have.

So I don't know if that information applies to ours.

Vacuum dashpot...??? Are you referring to the vacuum brake on the front of the carburetor...???  Does the car have Air conditioning...??

If so...When the AC is turned on..The plunger extends...To adjust the idle speed to compensate for the drag of the AC Compressor...It can be adjusted by turning the plunger with the proper sized wrench on the hex head on the carburetor end of the plunger...

Counter Clockwise will idle the engine faster...Clockwise will slow the engine down...Must be adjusted to the proper idle speed with the AC Compressor running...

TLBT..
