Probably still not the whole story. I'm learning it with you all as I investigate lol. No apology needed. Still gotta figure out what design this is or if there's someone I can call for it. It may be that he was told this specific unit needs broken in and can't be adjusted like an oem one. Looking for OEM ones like the previous one I could only find one source with rebuilt ones. There seems to be an adjustment screw on top of the aftermarket one, but I don't know how to use it and don't want to fiddle with it blindly.
