could someone please help me out? ASAP TODAY My pull cord broke on my Exmark viking walk behind. i would try to take it to the shop but i was thinking about fixing it myself. i don't know how hard it is to repair? also by taking it to the shop i may lose a few days. the goal is to get it back in service asap but i only want to do it correctly. all tips & info would be a giant step in the right direction.
