HI,
Just might have to readjust it,, Can you push (with your finger) the choke butterfly closed all the way? if yes then look at the linkage see if there is a bent rod on it holding it from going all the way closed Or adjust the choke to where it closes all the way (but not tightly). does the choke brake work?
you may have to readjust the fast idle as well once you get it sorted out..

good luck take care be safe

HI ,
YOu can always make the choke close/richer by adjusting the choke but getting it open all the way may be a problem, May be a bent rod on the buttterfly...
What I would do is get it to full running temperature and bend the rod so it is fully open. then set the choke so it goes closed when its cold and the choke brake opens it like 1/8 to 1/4 inch. and it should open all the way when warmed up.. try that

good luck take care be safe

HI, Just an addition to my above.. the rod on the choke butterfly is kinda bent anyway and sometimes it can get straighten and is suppose to be bent.. so bending it shouldn't be a problem.... the cam that the rod is attached to by the adjustment spot can only hang straight down ... so if the cam is hanging with the rod straight down at the bottom, the only way to make the butterfly open more is to bend the rod.. Had to do that once on a carb before so it would open all the way when warmed up..

good luck take care be safe
