Carburetor Needle valve adjustment tool needed

I have a Ryobi ss30 string trimmer. I was having trouble with the thing idling and dying with throttle application. I removed, cleaned and reassembled the carburetor and adjusted the high and low needle valve screws. It now runs perfectly. My problem is that I can not find the proper tool to turn the needle valves. The "double D" carburetor tools that I have are too thick to fit into the holes where the needle valves are located. Does anyone have a source as to where I might find the proper tool to turn these screws?

What type of heads do the screws have, D, rectangle, spline or something else, there are a lot of "rigs" that can work. Have a good one. Geo
