Hopefully, Jimmy will chime on on the frequency valve check procedure. I suppose one easy way to see if it is working is to see if the fuel return line is sending gas back to the tank at idle. If the frequency valve isn't operating, then the fuel wouldn't return from what I recall, and you would go stupid rich.
Like I said before, we put Porsche barrels in our fuel distributor, machined out the bottom, so the frequency valve isn't there anymore. So, I have no way or need to check it.
Was the warm up regulator full of that dried up gasoline? You can try to clean it out, but ultimately, you will want to send your stock FD and warm up regulator to CISFLOWTECH and have them do a service on the units. They match it up, make it flow right, then you know you have the heart / pulse of that nailed.
In the meantime, besides doing the flow patterns on the injectors, you should do the timed measurement. I use clear juice bottles that are a size that fits in the area, and doesn't strain the lines. Set it up so you can jump the fuel pump, then lift up on the arm ALL the way with one motion, hold for 30 seconds, then let down the meter arm. Kill the pump, and carefully remove the bottles, put them up eye level on a flat surface and see if they are all the same level. Yeah, you need identical bottles in order to see the level stability. Hopefully, they are all the same.
Then, do a crack open the air meter, just so the nozzles barely flow on a 30 second test and see if you collected the same amount. Given that you did, that would be a good sign. Take the amount times two and you have a 60 second test.
Oh, and pour one bottle into a graduated cylinder for measurement, then add the other four one at a time to see if it all adds up to the same amount per cylinder.
After we pulled the 1981 turbo off the tree, I started the procedure to wake it up after untold years of hibernation. Began with the fuel tank and after adding some gasoline, jumped the fuel pump. After a short time, I heard something under the car, it was spraying gas out of the accumulator. It was a scramble, it appeared there was a gallon on the floor, I was terrified we were going to BBQ. Good thing you got that accumulator swapped in.
