AFB Accelerator pump issues

No problem with parts of service but my problem remains. The basis problem is the accelerator pump well is not filling. I replaced the accelerator pump and placed an aluminum ball in the ball check of the accelerator pump well but the upstroke of the accelerator still does not pull the ball of seat allowing the pump well to fill with fuel. As an experiment I modified a spare ball check deleting the spring it seemed to work OK but until the ball is pushed back on seat some fuel is being pushed back into the float bowl. However the squirt of fuel is still better that before. My next experiment I am going to modify the ballcheck ( the one without the spring ) to limit the ball travel so less volume will be needed to push the ball to the seat. What do you thing??
