OK, here is my problem... I am running an OS 70FS and need to run a VP-20 because of the level of my tank.
The engine runs well with the high speed needle set at about 1 1/2 turns open. I connected the VP-20 and set it open about 5/6 of a turn from fully closed. At this setting I had to close the needle to 1 turn open to run well. I assumed that the pump was pumpoing way to much fuel so I closed the pump about 1/6 of a turn and returned the needle valve to where it was pre-pump. The engine would sputter and die after I removed the glow plug battery. Any Help would be great! This is my first FS My Goal is to get the Perry working.. not spend more on a regulator

Thanks
