i have a PM5, dye throttle, and dye on/off. i have not used any of it before. when i gassed it up today, air was leaking out of the screw opposite the macro line attachment on the on/off. i tightened this screw, this caused the hissing to decrease, but i could still hear it. i tightened the macro line too, but it would still not fire (with a ball in) and the hissing could still be heard, slightly. what should i do?
