hi guys, i have a couple of question regarding the numbering used on jet needles.... if i have a 6DH-4 needle, where does this fall in the range- rich or lean.... when the last number is higher does this mean that it is for richer or leaner... thanks for the help...[thumb]

I'm no carb expert by a long shot, but I don't believe it's that simple. The last number on the needle is the revision that needle was cut to. It could mean the taper starts in a different spot from a previous revision. There is plenty of info on line about this. You should Google it and read up on it, it can get confusing real quick and I can't type that much!!!
