The other issue is that it is not indexing far enough every time. Its not that far off 1/16"-1/8". every few shots it lines up wrong and "SPLAT" I get to clean. I don't even know how to start with this one.
The screw under the valve that faces the hammer, it just adjusts how far the hammer travels. If it's all the way in that's the highest fps you can get without a new spring.
