I may not be reading your replies the way you mean them------------

But, your answer that its a new carb does not answer the question I asked----
it probably idles at 1400 because of a high idle cam for while the choke is engaged--
then, after the choke is off, is the throttle plates closing completely or are they open some???????????????? After you explain those 2 items, we can continue to solve your issues------------


and--------was the electric choke kit added to this carb or was it stock that way????????(improper install)
