He means a rope off of a push lawn mower etc. u can just get the yellow poly rope and slide about 10 feet in thru the spark plug hole. Nake sure to take the rockets off. Thats with the piston down in the hole. Turn the motor over to raise the piston till its up enough to hold the valves shut. like PBR said snack the top of the valve to help loosen the keepers grip on the valve stem. Then go to it. Repete till done. kim
