Whether choked or not, sputters when starting up (regardless of temp), runs fine after 2-3 miles. If I stop on a ride to take a break, and fire it back up after 10-15 min, sputters and dies, then runs fine after a minute or so.
I have Cobra slash cuts and a K&N filter (just filter, no "kits").
Bike ran fine all the way from last June to this past February (when I had to use a bit more choke in the morning).
Have read in forums that an A/F screw adjustment is needed, but I am new to this. In the forums, they speak of "screw" and I am also wondering since it is a "twin carb", are there 2 screws?
How close are the recommended settings of "2 1/2 turns" given my setup?
Have not pulled the plugs yet as i am just beginning to research this. If they are "fouled", what is a good cleaning method? Or should I just replace them? If replacing, should I go stock, or is there a better brand or type? Any recommended gap change?
If environment makes a difference, I live in Florida and weather is generally mild year round.
If you have any pictures showing locations of the screw(s) I would appreciate it.
If anyone out there has been through this and can provide a bit of info, thank you for your help.

Here's a good link that shows you how to tear down your carb with good pics showing you what goes where.

Yep, I second the plugs. I was trouble shooting the same symptoms earlier this week and when I checked the plugs, I found that they were sooted black. Since I wasn't expecting this, I didn't have new plugs on hand. So I cleaned them with gas and a toothbrush, then sanded the electrode and negative with 800 grit sand paper. I also took that oportunity to regap them and the result is night and day. The bike now starts without the need to use the choke and runs super smooth.

I'm not sure about the dual carbs, the stock bike is a single carb. If you get the A/F set right you should be able to start just by twisting the throttle three times then pressing start with no enricher. Just use the throttle for a few seconds to keep it running.
