Edelbrock Air Gap on Magnum 318 Problems

I have changed the squirters but I think I went too big since I only had one bigger in my cabinet. I may order a squirter tuning kit and see if I can get it to work better. I tried a 1 inch four hole spacer which was supposed to help with my problem - (velocity) but it didn't seem to help which points me back to the squirters or/and pump cam.
