I adjusted it so I could push it open with my own breath.
Though the valve is small, I haven't had a problem with sludge/oil/water blocking the valve. It makes a funny buzzy sound so if the radio isn't too loud, you can hear it working and then i'll just ease off with the throttle.
You'll probably find in a store that sells pneumatic tools and accessories. If you search more, you probably could find a valve with a better smaller adj. range but there aren't many shops selling these in my area.

Here a picture of the valve itself:
How long has your fix been in use, does it work in very cold temperatures?
Where exactly did you slice the T connection in, am thinking the highest point?
Would you post a few pics of your install as reference for others.
