if you no so much about suck and blow you would realise inlet side only sucks thats how it creates a vacuum and if you no  so much about cheep vacuum guages then you will realise im right as you set them on a carb not to zero just off the stop needle that is not where you need them to be accurate you need them to be accurate at the vacuum reading the carb gives but of course being a motorbike mechanic and rolling road operator means nothing to balancing carbs you need to no about aircraft's to do that  :z
