Did you try riding it with a bit of choke? Did it make it run worse or better? You're using the choke to try and figure out if it's running too rich or too lean. That will tell you where the problem is. If you want to test if the old air filter is the problem just take it out and go for a short spin to see if there's an improvement. If there is then the filter is blocked. I'd be surprised if it was the filter just because it was ok before you did the carb work right? So it should still be ok unless you blocked it somehow. 1/2 a turn on one mixture screw wouldn't be enough to cause a big problem. They're an adjustment point they don't have to be exactly at 2 1/2
