I'd guess Jonas and Randall are on to something with the intake
manifold not being flush.
If after cranking the engine the plugs aren't wet, and if the float
chambers are full as you said, then your mixture isn't getting to the
cylinders. Can you feel gas at the bottom of the intake manifold or
smell excess gas or feel a gap for that matter?
