Air:Fuel Help. Cannot Get it Rich

you can spray water too and find the leak, just set it at a low idle for max vacuum and spray water in a stream onto the check points and listen for a drop in RPM's. Hey, itll clean the motor too. The power valve is supposed to richen 8 jets on activation. Is it working? Low vacuum is supposed to open it up as the high vacuum sucks it shut against a light spring.
