Is there some way to adjust an automatic choke?

Answer

yea easy job if its a carb.but the car engine must be cold when adjusting. both electronic and water chokes are held on by a pinch ring with 3 small screws, loosen the screws so the choke turns.turn the choke until the tension on the choke butterfly (the brass flap on top of the carbs primary venturi) loosens ( keep tapping the butterfly down to check tension) if the tension increases ur turning the wrong way if the butterfly opens your going the right way but youve gone too far the butterfly should be only just closed. if u mean the idle speed when cold is too high (sounds like over revving) then there is a small screw located behind the choke mechanism located this first u may need a small mirror then start the car and turn the screw until the engine revs about 1200 rpm but be quick and dont rev the engine or the choke will come off and revs will lower anyway so u need to switch off the engine and wait for it to cool a little bit b4 re adjusting hope this helps
