Clipper tickover

Can anyone point me in the direction of the tickover adjustment on a 1.8 clipper, its got a 2e pierburg carb and I cant find the adjuster anywhere…….pic would be great.
Shes ticking over at around 1100rpm wnen fully warmed up so need to wind it down a bit.
Cheers all..

Looking at the engine with bonnet open towards the left side,



look at left hand side of the carb to the rear the large disc shaped object  should have a nut on the back of it  that will adjust idle speed. It's a tight squeeze but you can fit your hand behind and adjust with a small wrench/spanner.



Sorry I cant remember which way increases or decreases hope all this helps
I'd say be very careful as any adjustments can have a knock on effect on the carb.
