04TRX400EX

I don't even know what to search for so here's the question ...
My 400EX was sitting for awhile while I was doing some modifications (like 2 months). When I rode it last week, it was really "sluggish" so I determined the carb was probably clogged from the gas breaking down. I drained the gas tank, took apart and cleaned the carb - float bowl, main & needle jets, linkage area, etc. - and also cleaned the air filter and changed the spark plug since I thought it could be fouled.
I had a very difficult time starting it this morning and getting it to idle, and once it did, every time I gave it some throttle smoke would come out of the exhaust and the engine would "miss" (like the the carb was flooding or the air/fuel mixture was off) to the point where it almost shut off. I'm not sure what I haven't checked and what's wrong with it now!
BTW, the valves were just adjusted too, so I don't think the problem lies there.
Anyone have any ideas?
