I’ve got a ~6 year old Craftsman 24" 2-stage with a 179cc engine. This season it’s been running a little poorly. I can only back the choke off about half way or it will die, no matter how warm it is. I took the plug out and it looks fairly dirty so I figure I’ll put a new one in and see if that fixes everything. Do I need to use a specific Craftsman plug, or will another one work just as well?
