Need choke/ need to remove ol' stuck one

[Sean1965]

I got my bike running but since the choke is seized it requires me to be constantly adjusting the air mixture screw as i warm it up. Any suggestions on how to get the old one out (it is real jammed in there). also where can I get a new choke assembly? Thanks guys.

Try penetrating oil for a couple days, then some heat, too.  Keep in mind it has a rubber seat, so keep the heat below about 400 deg.
