So I know they don't have a "choke" as such, and I believe the "wax" stat operation is effectively the "choke". My car starts and runs great when cold - IE additional revs to keep it going, and when fully hot runs fine, revs drop to 750/800 rpm. BUT - in the middle bit, not quite fully hot, not fully cold, it has a tendency to stall as the revs are too low.
Is the adjustment in the "wax stat" area? If so how?
