NO, NO, NO, dont drill anything, remove the engine shroud, turn the rope pulley in the direction it would go if you were pulling on the rope until you cant turn it any more, now back it up until the hole in the pulley aligns with the rope entrance hole, now hold it there( use a c clamp or something) thread the new rope through the holes, tie a knot, release whatever you used to hold the pulley and you are done, other than putting the shroud back on. Have a good one.
