So I lost the third post screw for my reomizer 4. I found a screw that would fit it and screwed it in the empty post while still using my single coil. My coils started to fail and wouldn't fire so I removed the screw and now it's fine. Is this because of the make shift screw I'm using or is there not suppose to be anything in the empty post on a single coil? Just wondering before I attempt my first dual tonight.
