The choke cable on a Series I through III Lambretta runs from the choke lever on the right side of the glovebox, to the carburettor on the right side of the engine. The cable has two small soldered nipples on each end and must be a specific length to work properly. When the small choke lever is turned on the frame it simply pulls the cable by about a quarter inch which allows the starter jet to be activated and provide a richer mixture for starting.

To make things easier it is a good idea to remove the air filter so you can get access to the point where the choke cable connects to the carb.

Once the air filter, or at least, the air filter tube is out of the way you can start be removing the choke plunger from the carb body. Using a pair of pliers or a small metric wrench, unscrew the plunger assembly from the carb body by turning it anti-clockwise.

At this point you should be able to bend the cable where the spring goes into the carb, and pull out the spring and the small brass plunger. If your cable has actually snapped it may be tougher to remove the plunger. You may need to remove the carb to shake it out while holding the carb upside down.

Remove the brass plunger (red arrow) from the end of the cable pushing the small end nipple out of the hole just under the spring. Once this is removed the spring, adjuster (blue arrow) and 90 degree bend tube (green arrow) will all be able to be removed. This will release the slack on the cable and allow you to release the other end from the choke lever on the right side of the frame.
