A Holley problem all should know about and Why Holley Tech S#@KS

I had the same problem. 225 Slant Six with a Factory Hyper Pak with a 650 DBL Pump. Solid motor mounts. It really started being a problem when I installed a Y pipe on the header outlets from flow master. Never noticed it before that. I thought that was the reason, but now I think it might have been this check ball deal. At certain RPM's it would just spray fuel and I had the clearance on the pump cam set real loose. You could hold the lever off from the pump cam and it would still spray fuel. Thanks for the heads up!
