Before I put on the AFR gauge I pulled the carb and checked the slot. There was too much on primary so I squared it up. Turned all 4 corners to 3/4 out. Idle jumped to 1100 so trimmed down with the secondary adjustment. Checked the mix with the vac gauge and ended up leaving them at just less than 3/4 to get the AFR to 13. Going all the way in will kill the motor.
