I had a problem with the idling speed on the Pytchley, this has an SU carb but the problem could have been with any type of carb.
I set the idling speed in the usual way looking into the engine compartment with the nearside bonnet half open.
Having set it, I then got in the car and took it for a short drive. I found that the engine was idling much too fast.
Got back to my garage, opened the bonnet and it was idling okay.
I realised that when I sat in the car the engine speed was increasing. The carb is perfectly okay.
I adjusted the throttle linkage slightly and the problem was cured.
