It’s all good, buddy. Check the cable (internally) they do go bad and get rusty and start binding
A new cable may be all you need, but please check your clutch lever operation as well
I saw another kart with the same set up as yours, and it totally goes through the steering wheel
The end of the cable came to the surface and had a cable clamp, with the excess left over cable zip tied to one spoke of the steering wheel.
Honestly I don’t think the newer karts you’ll see in Vegas may have this set up, but I could be wrong.
Here’s a link to that kart, check out the steering wheel on the right side bellow the Mychron
