I'm finding that I'm having a hard time tweaking the water to my wet headers. I have a ball valve before the T valve. The spring and ball in the check valve are just a few years old. I know you can put jets in the headers to restrict flow but I was hoping to change the spring to a stiffer one for a bit more control. Right now I'm trying to set the water to come in at 3k. Just trying to get a bit of mist. But it seems to go from nothing to too much by just opening the valve 2-3 degrees. Anybody else done this? What spring pressure is a stock spring? Any other springs for other applications that work?
