Rich/lean carb setting screw

Hey guys, kinda new to the forum scene, also this 2003 Volusia Limited Edition. I got this bike a few years back from a fellow in Florida. The bike runs great but it has two small issues. 1. After the bike sits for a couple of days, it's almost impossible to start. I have tracked it down to a problem with the vacuum petcock. I just rebuilt it and it seemed to work great the first time, but then started doing the same thing the second time I tried to crank it. It killed a brand new battery and just barely started to fire once, or twice before the battery went out entirely. Right now it's still on the charger, and I haven't tried it a third time. 2. Bike runs good after you get it fired up, but really needs the choke on a tad. I've traced that back to most likely being an ill adjusted carb setting. The owners manuel says that a screw just behind the fuel petcock is for adjusting the rich/lean mixture for altitude. And sense I'm not the original owner, I would like info on how to set this back to factory settings. Any help on both these matters would be greatly appreciated.

You don't state how many miles you have on the bike right now, but one thing is known. It is 16 years old. The bike is cold blooded by nature and SHOULD require the use of the enricher circuit (it is not a choke), but you should be able to run with it off, once it is warmed up. The issue of it not wanting to start is most likely NOT your petcock or the idle mix screw, but instead the pilot circuit in the carb. Adjusting the screw won't help. You need to pull the carb and possibly replace the jets.
