Don't know how it could be since I've not only got the lid on but the snorkel too. I'm thinking either it's a needle issue or my slides aren't opening all the way.

its probably rich on main jets. how do the plugs look

That's what I was wondering too but wasn't sure. Honestly I haven't gotten a good read on the plugs because I can't get any real good RPM. I'll work on that, it's got 280s now with 25 pilots.
