Another thing I have found with these carbs, every so often I get one that will not work for some reason. I can see no reason why they won't work. I can take all the parts out of that carb and fit them into another body and it will work fine. It has to be something wrong in the body but there is nothing visible that I can see. Not a problem for me as I have countless carbs here to play with but if somebody is modifying their carb and it doesn't work there is always this issue to keep in the back of your mind
