So.. lemme get this right? The one from Napa is stranded wires... but there are others that are solid core?
The local small engine repair man said that I already had solid core (dunno how he knew that when he didn't know where my clutch was). It looks to be pretty thick, 6 or 7mm... but my terminal still looks messed up to me. If I can just find a good boot/terminal, I'll just change that first & see if the wire really is solid core or not. It prolly is, 'cause it seems pretty hard to bend.
