This slider sits inside the throttle housing at the bottom. The cable comes to it from the carb, on one side is a raised tongue that is horizontal on the block. This tongue goes into the throttle tube which has a corresponding slot so when you turn the throttle it slides the block along and opens the carb. I cant understand whty they used such a cack handed way of throttle, i have a brass slider and had to buy a remade tube, after much grinding and filing i managed to get them to work together but the action is notchy at best and the throttle doesn't snap shut on it's own. I think that's why you see a lot of quick action throttles on todays Lunas
Also if you choose the original method you need a tube at 45 deg at the back of the throttle housing to guide the cable outer to the right position Rolling Eyes Rolling Eyes

Thanks thackers. Sounds a pain. Now I have to have a think about whether to go the quick action throttle route. Would you still use the throttle housing if you did use this method?

No, i dont think you would use the housing there wouldn't be enough room on the handlebar

they are known as worms Laughing its a horrid set up, the pictured one looks like brass i think some got remade in brass and others in alloy.
they are a pain to get working well, and my current one took several hours of filling with grease and grinding paste while fitted to the carb so it could grind its own smooth way.
i will also possibly try a vespa clutch spring instead of the dellorto carb spring for the slide, might work, but probably not, .......... nothing ventured .........
