Probably need a good carb cleaning and maybe rebuild. Something that would be a good idea upon purchasing a used sporty with a carb.

Took it apart yesterday and looked at the jets and it has a 48 slow and a 185 main. The harley dealer told me I should run either 45/48 slow and a 175/180 main. Could it be that the main is dumping way too much fuel for just cruising around?

Changed the jets and still having the same problem. I really don't want to get a new carb cause I really don't want to spend a lot on this thing. This damn thing it starting to get really aggravating! The Harley dealer close to me wants over $200 to just look at the damn thing and if the carb has to be rebuilt they said it would be about 5-5 1/2 hrs of labor plus parts. For that I can get a brand new S&S carb

Your jetting is fine. Not optimal but it won't create such an annoying issue. CV carbs are pretty much bulletproof if they're clean.

Did you have this issue before you changed the plugs? Did you check the plugs IMMEDIATELY after experiencing this problem? If you run it smooth then check the plugs the signs of a fueling problem will disappear.

I would suggest removing the air/idle screw to see if the point has been damaged. People that aren't familiar with CV's will crank it in tight then screw it out. The slightest damage to the tip can create havoc.

What jets should I use then? That's what the Harley dealer told me I should run.
Yes I had the issue before I changed the plugs and when I did 1 was white and the other was black.
The air/idle screw could really make that much of a problem if it's damaged the slightest bit? If I don't notice any damage to it what else should I check then?
When I pulled the plugs back out after changing the jets they were caked with soot.
When it sputters it will blow a lil white smoke out then it will be fine and if you do it again it will sputter and then blow black smoke out. Which I know white is lean and black is rich. Should I try upgrading the plugs?

What year?
Oil dump may be wet sumping from a weak spring, old ball, or bad seat on the check-valve in the oil pump.
Take the carb apart and clean everything....make sure the jets are clear. <edit....sorry just read that you changed the jets......>

45/180 if you have a high flow air cleaner and pipes with two turns out on the mixture screw. And yes, the slightest damage on the tip of that screw will basically eliminate that adjustment. But I don't mean microscopic. A visual inspection will eliminate or confirm that variable.

There are other problems you may be having but knowing the carb is correct will rule out a handful of maybe's.

I think it wasn't jetted correctly and the carb is basically shot. It's the factory carb and it kinda looks like it hasn't been cleaned since it was put in.

Your needle and seat are not shutting the fuel off. Take the bowl off agian and make sure your float is still connected.

Pull the bowl, use your finger to gently push up on the float, turn the fuel on at the petcock, and lower your finger to watch the fuel flow. Purge the dirty fuel a couple time to be sure to let any little debris wash thru. Shut the gas off and replace the bowl. Turn the fuel back on and confirm it is not still overflowing the bowl.
