Bern, he means the end of the low-end needle is flush with the side of the carb. I own a 12CVR/slide carb. I beleive "break-in" settings are 2 out on the high end needle. I left my low-end needle like it was during break-in and after break-in I started leaning it out(low-end) to get some punch. It's now 90 degrees in from factory settings(like it was when it was in the box). Then just tune your idle stop screw to get a good idle. If you screw out the idle stop screw to far the car will have a hard time idling.
