W108 250S Air con idle control

Post by VFRBoy » Mon 11 Sep, 2017 4:43 pm

HI guys,

I am having air fitted and wonder about the idle speed control. It's a manual so doesn't have a thingy to bump the idle speed like an auto.

The compressor is a Hall type so not great efficiency and a bit of drag.

Is there a part that can bolt onto the carbs to increase the idle speed when the compressor kicks in to overcome the extra drag and prevent stalling?

Cheers
