Quoted From moparfan:
to set the choke you fully warm the engine pull the air filter assembly off and see if it is fully open. if not then reset it by loosening the 3 screws and turn till it is fully open. you cannot just “guess” where it should be. the choke will not change just because you hit the brake or turn a corner. it would more then likely be in the float ajustment. a model number of the carb would be helpfull here.
I’ve never heard of setting a choke when the engine is warm and honestly I think it’s better if you adjust it when it’s cold but you need to get the plate tension just right for it to work properly.
That said you could have a problem with the linkage that actually could be the result of a misadjusted choke, if the choke isn’t adjusted correctly when the engine is warming up the fast idle screw will not set properly. In short I would check your choke adjustment first before making other adjustments.
