Anybody got a suggestion on how to speed up a slow sticky rotary valve? I have one that sticks when opened. I have pulled and cleaned it and applied a light oil. This freed it up some but still not enough. This is a miraphone 186-4u, should the rotor when unattached to the lever be able to spin all the way around? Mine will not - that may be the problem. Possibly the cylinder could be out of round?
Any ideas?
