choke cable problem

[solorider]

I managed to buy a used switch asm for a choke lever, but the choke is very heavy to pull and it feels like the lever will break, the cable has some stiction but not over tight, I tried lubing the cable with no luck so I bought a new pattern cable and that feels rough, I haven't fitted it yet. also when I bought the switch it came with an extra item but I don't know where it goes, my original switch has nothing like it either, here is a picture of the offending item



any help would be appreciated
