Chip,
1. Check idle air bleeds for obstruction
2. Check accelerator pump adjustment and function
3. check pump discharge for obstruction
4. check timing, if timing is still same then go up 1 size on squirter and see if it clears up. If weather is close to prior runs and this did not happen then I suspect timing is off or trash in circuit somewhere. If DA is different then it could be a lean condition and squirter size change should help.
