I posted this a couple weeks ago, based on the Weber Jetting Survey thread. Keep in mind, the Column that says "overlap" should read "Lobe Seperation" I was in a hurry & someone wanted to see the comparison so I posted what I had... Anyhow, if you look at the chart you can see few similarities that stick out. Most notably, to me was the Lobe Separation to Emulsion tube. Good Luck & read that thread under the Weber Tuning section under this site. Some good info in there. Let me know what you come up with & I'll add it to the list. url=http://www.clubcobra.com/photopost/showphoto.php/photo/76592]
