Hi
I'm trying to tune my standard 316 83 carb with auto choke it's running way to rich I believe and could do with adjusting the auto choke if possible and idle,if someone could tell me which screw does what? there is only one I can see on the rad side bottom right of the carb but the others I can't see? Any help would be great

If i am correct you have the solex 2B4 on it.

To adjust idle you need to move the screw which is at the throthlelever.


The small screw which is placed at the front is the mixture.

Autochoke is more difficult because there are lott of different items that must work seperatly and correct.

That's really helped me out,thank you very much,the mixture is the one toward the radiatior side of the car,the car has a little back firing thing it does,I think once the carb is running a bit better I will have to do the timing
