Chris - I just had another thought...

If you got the gasket on the float bowl backwards, the port that passes the fuel from the accelerator pump to the metering block will be blocked off and you won't be able to pass fuel.
Easiest way to tell if this happened is to pump the throttle while watching the accelerator pump lever to see if it moves and the nozzles to see if it is moving any fuel through..

Good luck
