I don’t know what machining capabilities you have, but, I’ve done this in the past….Machine a part that looks exactly like the spool you refer to, but make the center bore as close in diameter as you can to whatever bowden cable you plan to use. Drill and tap the hole where the locating screw goes that locks it into the steering handle. On the opposite side, drill and tap and use a set screw to lock the bowden cable into the spool. There’s not a lot of pressure on that cable because it is also clamped at the carb end. All it does is hold the bowden cable inside the handle.

The other thing is to look for cheap parts motors like Speeditwins that are toast but have parts. Your motor looks like the one for sale at Tomahawk.

George, the motor did indeed follow me home from Tomahawk.
I installed the smaller cable in the original spool, using a plug
made of Delrin in the bolt hole in the outside of the tiller handle
that locates the spool. The Delrin plug “squishes” just enough
to hold the cable without crushing the cable.

I’ve contacted Aircraft Spruce about their cable, with questions,
and supposedly there were going to contact the manufacturer.

Prepare to be boarded!
