My choke runs out the bottom and the only thing holding it on is a washer and the end cable nub – so if you do it that way you dont need those parts – just need the choke slide and the spring (should be inside the carb) and you need the plastic tube that buts up to the end of your cable sheath and then pushes the choke slide when you apply the choke. You could probably make that out of any piece of copper/aluminum/brass tube… Thats what i did to make the guide for my throttle cable. Look at my pictures on that thread.

either way you install that cable, I dont think you really need hardware. I will try to explain its kinda hard. This explanation assumes you have a cable sheath on the bike, if you dont – you need a replacement. Look at 1977 or mopedshop. Also I will explain it like mine with the cable coming out the bottom – to have it come out the top I think you can just flip direction.

1. Get a bike cable with the metal nubs at each end – cheep and easy any bike store, like 3 bucks thats for the nice stainless steel ones
2. Cut one of the metal nubs off, make sure its a clean cut i.e. dont let cable fray (i usually put a drop of 2 part epoxy on the end and let it harden so it cant fray)
3. Slide a washer on the cable – this washer should have a small enough inner diameter so the cable nub cant get through, and large enout outer diameter that it cant pull through the carb
4. Thread cable through carb cap, through the choke spring, through the choke slide and out the bottom of the carb.
(if you want it going out the top reverse the threading order and have the nub and washer at the bottom inside the carb there up against the choke slide)
5. now you need to have a piece of tube or something abuting directly with the carb slide and then tight against your cable sheath (if your doing it coming out the top just have your cable sheath tight against the carb cap)
6. thread the cable all the way up the sheath to your controls, pull out the slack and attach to choke lever. you have full range of motion with moving the lever/controlling the choke.

Ok so this got way long and is confusing – heres the underlying concept – The little brass slide in that hole, that needs to move when you push the choke. When you push the choke youre pulling that cable in, which will pull the nub/washer closer to the carb end of youre cable sheath—> moves slide

I hope this makes sense. And do a really good job cleaning the carb before you even begin running cables.
