hey guys i have a 54 7.5 fleetwin model 7514. the motor runs great but i cant keep the starter rope on. i have tried every knot i can think of and nothing seems to work. it will stay on for a day or a week but always comes loose. also i have a rattle when run with cowl on and have added bumpers of one sort or another everywhere but cant seem to get rid of it. it purrs like a kitten without the cowl
