Can't think of a better description. With so much chatter going on regarding throttle cables, today I installed a new throttle cable because my old one has always been too short in length. It was a straight line between the firewall and the carb. Have been wanting to install a longer one which would allow a nice round curve down to the carb.
The issue I am having is the inner wire is too slippery. If I pull the throttle knob out, it will not stay in it's pulled position but instead goes back to it's close position. The strength of the throttle spring will close the cable back. Not enough resistance inside the cable sheathing.
Argh!

Disconnect the carb end of the cable and pull the knob out far enough to expose a bit of the wire. Then put a couple of slight bends in the wire, push the knob back in and check to see how much resistance there is. If it still won't stay when hooked up, repeat with a little more bend. Go slowly, to keep it from getting too stiff.

You can also put a small shaft collar with an Allen setscrew over the cable housing, and tighten the set screw a little at a time to increase the friction. That will be a more accurate way to control the tension than bending the cable. Jerry

I did the kink method and it worked. Mine only needed two kinks but be aware you want it on the loose side because mine tightened over time.

Yeah, I totally forgot that I did the inner wire bending idea on my recently retired cable about 30 years ago. Yes, it got harder over time but that was probably due to lack of use.

I slightly kinked the new throttle cable in a couple places and it is working great. Didn't go too crazy, just enough to hold the cable still. Thanks everyone for the help.

I squeezed the housing before the flexible cable starts. It's stiffer for sure but I don't like the feel of it in the fast idle position. I think kinking the wire would be better. HRL's method sounds good but I haven't tried it.

These photos show the original throttle cable out of my signature 1955.1 3100. Note the punched-in dimple in the outer cable sheath, to add friction to the inner sliding wire. It worked fine until replaced last year due to broken/shortened inner wire at the carburetor. For the new replacement throttle cable assembly, a dimple was center-punched in the outer sheath similar to the factory original.
The new throttle cable works as before and holds its position when pulled out.
ol 55, I like the idea of center punching the outer sheath. Another option. Thanks for sharing.
