Here are a few pics of my latest way of securing the throttle cable.
A length of brass strip is bent at one end to a hook shape.
A 5/8" length of brass tube is soldered into this hook.
This mount is then screwed onto the pylon, as close to the link as feasable.
A 3/8" length of fuel tubing is slid over the cable housing.
The cable and housing is then put thru the brass tube on the mount. The piece of fuel line is then pushed onto the brass tube to secure it.
Another piece of fuel line is put in place on the cable housing and brass tube on the other (throttle link) side.
Attach the throttle link to the throttle arm.
