Check your float levels - sounds like they might be set too high - allowing gas to slosh out into the carb throats. If you do not have the clear float (see through) screws in the sight holes - I recommend them. You can (carefully) adjust the float level while the engine is running. You do need to be very careful when loosening the float level locking screw on the adjustment bolt - but it can be done (if you loosen it too much with engine running the pressurized gas will push past - possibly hit your hot manifold - NOT a good thing). Go to the Holly website for specifics on float level adjustment.

Hope this helps -- been there - done that -- and it worked.
