Not airplane related, but you guys hold a lot of wisdom. I have my thoughts, but I can't find proof. With regards to a vacuum: I am trying to sync a dual carb motorcycle engine. It appears to me that one of the carbs has a smaller diameter port in which to attach the hose than the other. If the inside diameter of the tubing used in a in a 2 bottle water manometer, given the same vacuum pressure from the source, would the smaller diameter hose suck harder, or more water? I think so, but can't find proof. My experience would tell me that it is easier to suck from a straw rather than a garden hose......
Thanks guys!
