Remove the Phillips head screw under your choke lever and retrieve the wave washer and other small parts there. The cable, with a large trunnion swaged here will come away from the lever.
The Carb end is more difficult... You can opt to remove the
fuel tank, pump, cable bellcrank bracket (screwed to the top of the carb) for better access. If your fingers are small enough you might try without so nuch removal but your objective is to unscrew a hexagonal connector that holds the cable/spring and choke plunger in the carb.
Pull back the dustboot over the cable and you'll see it.
You should be able to use an open end wrench to loosen it then use fingetips to unscrew it, take care when removing the whole lot from the carb- the spring and choke plunger sit on the end of the cable held only by a small 3mm swage. remove these parts from the cable and pull the cable out through its guides along the frame. Assembly is the reverse. I hope this helps
