As above rebuilding a solex carb and wondering how you test and set up the choke unit, put a negative to body and positive to terminal but there is no movement to choke or spring when tested off the car or spare units. Stays closed see pics? Is this because the ambient temp is warm enough (about 12 degree in U.K.) I lined it up on carb so the bit on the spring is just touching the prong on the choke shaft so it remains closed .
