ok so after installing a 366 spring I had to fight the fuel screw to get it back close to prior settings. the previous owner has evidentally played with it quite a bit as it lacking threads past nut and the end is completely rounded off and the flathead slot is even gone, is there somewhere were i can get a replacement and turning the screw inwards towards pump is to increase fuel and backing away from pump is backing the fuel down as well correct??

 

go to a local injection pump shop that deal with Bosch parts and you are correct, in = more fuel,out = less fuel

 

When you go to a Bosch certified rebuilder they will want the serial number off the pump - hope you can read upsude down.
