The throttle, choke and decompress  cables need to be loosened from the handle bar side, and

pulled from the engine side to be removed. To install new ones, it's the reverse, you snake them

up the cable housing from the engine side. A bicycle cable cutter is needed to make a clean

 square cut so the end will not fray when trying to snake them up the cable

 housing. Use the adjusting brass round screw at the grip and decomp and choke assemblies

 to get the proper tension on your cables.

The brake cables need to be loosened from the brake drums and pulled from the brake levers

on the handle bar.

 Installation is the reverse, insert from the brake levers thru the cable housings to the brake

drums, do not forget to insert the cable housings in the little round  eyelets on the moped frame

to get the proper fitting
