Throttle cable

This section shows a quick step by step of replacing a throttle cable on a series III Lambretta. The one in the photos is an LI125 Special which has a similar headset to the TV and SX, but the images will work for an LI once you've removed the slightly different headlight rim.

Remove the upper 2 small screws that hold the headlight trim to the headset. The lower ones can stay in place or you can remove them too for easier access once the headlight is removed.

On the underside of each side of the headset you'll find a single flathead screw that needs to be removed. This will allow the headset top to be removed.

Disconnect the small light for the speedometer which is a friction fit, and then push the speedo cable up from the front fork to get enough space to unscrew the speedo cable from the speedo housing.

Remove the left side panel to get access to the carb. The throttle cable is the cable shown above with the red arrow. Now remove the inner cable by cutting one end or the other and pulling it out through the cable outer which will remain.

New cables come in a variety of ways, but you'll need to have a removable part at one end or the other. I choose a cable that has a soldered nipple for the carb end, and a removable nipple at the headset end.
