100 Throttle Cable seized again - options?

[CubbyRI]

Ok I fixed it at least for now.

1) loosen the cable pinch screw at the governor
2) remove air cleaner and loosen the cable attachment screw under there
3) remove the two throttle unit mounting screws on side of tower (backing nuts are inside)
4) turn the throttle and push the handle thru the slot to remove the whole thing
5) the outer cable unscrews from the throttle unit
6) pull out the inner cable with vice grips, if stuck, soak w pb blaster
7) run 320 sandpaper up and down the cable to remove scale and corrosion
8) make sure inner cable ends are bent perfectly straight (use small vice grips)
9) coat with anti-sieze and push thru, pull all way through, recoat, repeat several times

In my case since the end had broken off, I cut that much off the outer cable to match using Klein's lineman dykes

Reassemble and wait for the next time in a year or two!

I will try to source a stainless inner cable before then!

To free up a frozen one, shoot as much PB down the thing as possible. Then flex the outside back and forth along the length of the cable. The housing is springy so you can move it back and forth to un-freeze it.


I've never had this NOT work.

Are the 100's a jacketed cable? I like the idea posted earlier about covering with hose. Possibly some small ID fuel line once cleaned up and broke free. Shoot a little love yearly as a maintenance item, to keep things moving freely.

These older cubs at least are just wire-winded outside with a stiff wire inner. Jbrewer method opens the cracks and lets the lube soak in. I was looking for something more durable when mentioning covering the cable because otherwise water soaks in on that lower curve that hangs down exposed between the tower and the carb.

In my case see above, I think the sanding the inner cable and applying anti-sieze may help.

That said, I realize now that the cub should not just be left exposed anyway so I will make a breathable rain cover for it. Has to be breathable because a tarp will just trap moisture and make all of the tractor rust even worse. But a tarp open at the ends would go a long way...

Hey Rhodey ! Check this out. Google; Motorcycle cable lubrication tool. Would have to use it when it’s thawed out. Wet is ok. Only have to disconnect one end of the cable, preferably the higher end. I use PJ motorcycle chain lubricant. For me it has been good for several seasons. Good Luck! Steve .
