Running on 3 and low idle speed when cold - 200 1981

Thanks Rhys.
When the engine is cold and you give it some throttle whilst in park, revs increase without complaint.
Must be that auxilliary air valve.
I posted a new question ( auxilliary air valve - questions ) about that valve and it's functioning range, have been doing some experimenting !!
I think I'm near a solution or cure, depends on the condition of the bi-metal strip and its ability to move through the range to give me increased cold idle as well as being shut when the engine is at operating temperature.
Have now played with the adjusting nut on the side of the unit, will know tomorrow morning, or late tonigh if I've been successful.
cheers
richo
