Meaning this one:
Is there a way to get the coil head out. I could try to rebuild it but I'm not sure whether you can take the head out. It certainly doesn't seem to budge using only the fingers and I don't want to force it with any tools in case it is actually welded on.
Any input would be much appreciated.
