there is 2 sets of big butterflys, a top and a lower, if you open the throttle wide open then the lower butterflys will open, but the top ones wont unless it is on a motor and the motor is running. air thats pulled in the motor when you open the lower butterflys opens the top ones. if the choke is closed then the lower ones wont open eather
Sorry lt1s10 I missed this post!
