80dt125g

i have an 1980 DT125 that i have been restoring. took the carb out and cleaned it, new fuel cock, everything de-greased but keep coming up with the same problem. i use the choke out to start it and wait till it warms up and idles at about 2k and then when i put the choke in the bike dies. i can ride the bike with the choke out and it rides fine but once i put the choke in while riding and i slow down and downshift, the bike loses power and dies. anyone have any suggestions to try. thanks.
