2003 ski-doo 550F Fuel Issues

Hey guy's,
I've got summit 550 fan and I'm having a hell of a time with the fuel system. It sat for 5 years, I got it running last month but it would pull 35-40 MPH tops on hard pack. I just replaced all the fuel lines and fuel pump and i've cleaned the carbs twice. After I got it together a few days ago it would barley run without the choke on. Today I'm working on it and there's so much fuel going to it when I pull the plugs and crank it over its spraying out the spark plug holes. I'm just about at my wits end with this thing and I'm not sure how it could go to one extreme to another in a couple days without touching anything. Any help would be great.
Thanks
