I need a little help understanding which method would be the best way to keep fuel atomized for the longest period of time. I have a CV carb (more specifically a Keihin CV 40) and I'm wanting to install a Dial A Jet. *If you'd like to learn more about the Dial A Jet, go here, http://www.thunderproducts.com/dial_a_jet.htm [Broken]. Thunder Products (manufacturer of Dial A Jet) recommends putting the Dial A Jet anywhere between the 10 o'clock to 2 o'clock position and ideally 12 o'clock. Someone I had a conversation with wanted to place the Dial A Jet in more of a horizontal position (For example 2:30). They said that gravity would assist in a puddling effect if put in a vertical position. In other words a vertical position would allow for worse atomization. Here is what I'm confused about... If the Dial A Jet is placed in a position, horizontal or vertical, wouldn't the result be the same? It seems as though the vacuum is so quick that the moment the fuel reaches the end of the Dial A Jet it's being sucked into the engine.
