Frank,
the fuel bulb should be soft when running. Have you checked your blow & suck lines? They will cause havic! Also vacuum leaks & fuel pumps. The Mercury pumps hardly keep up when functioning. You checked your pumps for no crud in the check valves & some forget to replace the seating gaskets.
Oh BE careful with the lines with the check valves on 3 & 4 cylinders, the check valve could be put in backwards or not at all. They keep the reed plates from flooding unburned fuel!
