Looking for some insight on correct set up on a cube BV. I changed from a K to the cube and am unable to get the idle below 1900 RPM in gear ith out the surge. Need a ball park starting point. BV is way on the rich side at this time. Hilborn shotgun hat, hat nozzles with air. Port nozzles with 14 lb check valve. Timing locked at 30* 14/71 HHR blower on alky.
