Mils,

Buy whistles and put them in, Summit, Jegs or your local hot rod shop will have them. It's the back barrels (secondaries) that are causing the trouble.

Reset the float levels to the bottom of the window - normal. Give it a try. Lowering the rear float level an 1/8 of an inch would be worth a try but this may cause a starvation condition under full acceleration.

Fixing this is a little bit of experimentation at a time.
