Brent ... at 1500 rpm , isn`t he still in the idle circuit , and doesn`t it still have some effect up to about 2500 rpm ? If so , maybe richening up the mixture screws about 1/2 turn as you suggested will help a bunch .
On my 427 Galaxie with vacuum secondaries , if they dumped in too fast , the engine stumbled badly and then came on strong . Changed springs to delay opening and solved that issue . I also run 22 degrees initial timing and 35 max ( modified the advance curve ) .
