I have a new YS 63 4 stroke. After fighting it for a while I got it to run by opening the pump screw 1/2 turn. Now it's all out of wack again. I have run about 50 oz of fuel through it so far. It wants to start at minimum throttle only, then it seems to load up and die at mid and high rpm. The needle is right, but it still loads up. The low end needle is at about 1 1/4 turns from fully seated. I have tried to reset the pump, but I need more info.

Is there any place I can read up on how to set this pump correctly, how to set it back to a "factory" position, or any other info on the pump?????

I have finished my plane and I am getting desperate to fly it!!!! Any help would be great.
