If the piece of 5mm monkey metal used for the pump rod is changed to a piece of 6mm silver steel and the valve fully closed that was the result. Irrespective of what you think that was how it was for 20+ pumps.Not wrong as it happens when over pummped and dont know were you get 20 pumps from i screwed the pump valve by around 2 3 m closer to the near the inlet port this makes it less pumps for full power and if not messed with 20 pumps ya must have good right hand 🖐 as it be impossible to pump with out bending arm
Less pumps same or more power how in the right minde wants to stand there pummping some thing 20 times for one shot
