Just recently became interested in lawn boys last week when I bought 7073 off the side of the road for $40.00 and it starts, runs, and cuts great! Now someone locally has another 7073 for sale for $100.00. It is supposedly used very litle with bag and runs good, but the rope is broke. Would it be worth it? Would it hurt to try to start it with a drill and socket, to be sure it runs?
