How do you have the floats set? Do you get a trickle or a stream of fuel out of them? Verify the linkage is not hanging up anywhere.
Pull the carbs off and ensure that your throttle blades are not hanging up on the gaskets or manifold. Make sure your air bleeds are clean and clear of contaminants. Check inside the float bowls for contaminants.
Pull the intake and use the Hughes Engines intake sealing wax string or equivelent to verify fitment.
Do you have MSD? Are you using a standard dial back timing light or an MSD timing light?
