Picture below shows layout of the bus - implication is that the cable goes into lever and thats that - hole is about 5mm and the cable end kink is about 3mm so no way would it stay located? How do I fix it?
This is just an excuse to show off the shiny underside of your bus isn't it. Mine is ora nge - but it's rust not paint
Fitting a washer on the kinked bit, other side from where cable is crimped and then tension of cable should do it I would have thought!
I’d make a simple fishplate with a smaller hole in the bottom to suit the throttle cable and a bolt through the top hole, or weld the hole and redrill.
