you've already replaced it?
close the choke when you start the car when it's cold, let it warm up for a minute or so and then open the choke a bit or full if it will idle fine. when you drive the car you will know if it is boggy and needs more choke to warm up, or if there is too much choke and the car will not accelerate the way it normally does. just remember not to leave the choke partially closed when driving after the car is warmed up.
"Well done is better than well said." - Benjamin Franklin (1706-1790)
