For something that should be so easy, I'm having a hell of a time trying to replace the starter rope for an older briggs/stratton push mower. The recoil starter gear assembly is part number BSP-299948. I cant see how to replace the starter rope - there is about 18 inches of the old rope left (attached to the pulley). I can see how the old rope goes in a hole at the centre of the pulley and that there is a knot behind to hold it. However, the pulley looks like it is all one piece, and I cant see anywhere behind the hole to tie the knot. I phoned a local repair shop and they wanted about $35 to replace the rope! Any idea's? Just pay the $35? I'm thinking there must be a special technique for getting the old rope out and a new one in?
