Edward (part deux):

Sounds like you have one carburettor running very rich--did you attend 
to that?

If that's the case, this might allow the engine to start--with the more 
open throttle you established--even if the chokes are still not set up 
correctly.  Have someone pull the choke slowly whilst you watch--the 
first part of the choke pull should open the throttle as you describe, 
but the second half should raise a lever near the bottom of the float 
bowl, which pivots to push down the jet diaphragm and thus lower the jet.
