if you remove the airbox and then it runs fine it's because your too rich with it on. like James said try stepping down a size at a time until its gone...

The stumble is caused by too small a pilot jet and too restrictive of and air intake and that is made worse with a bigger cam...and you didn't mention your exhaust...
As you have witnessed all the stories about having to have an airbox for the stock carb to work right are bunk...it's just the opposite...the higher the air flow the better it works...with correct jetting and a tuned intake...
What you need is a high flow intake like ours that comes with a complete jet kit...
Makes great power even with stock exhaust...the jet kit covers all your needs for any internal/external modifications...

Stock needle in stock position...stock slide spring... 45 pilot jet... get rid of the junk...jet an air box lid delete adapter and clamp on k&n filter...adapt a 4" abs 45* elbow to air box lid and run pipe up and out the back for a snorkel...
Get our complete jet kit...and tune it for max power...!
