OK Guys. How do I get this broken inner cable off and a new one on? It appears to be soldered and crimped, but I'm not sure.

Frank - get a whole new assembly from TRF. Cable, pull, and knob. Believe me, it's worth it.

What I have done in the past is heat it up and pull it out. Then, I went to a guitar store and purchased the appropriate guitar string and soldered that in.

I'm sure that the price for a new one is cheaper and faster. Make sure you keep your original choke knob. The repro knobs tell you to "PULL CHOKE" whereas the original tells you "CHOKE".

I have heard stories where people have used pantyhose to replace a broken fan belt.

You are talking about a solid cable, my choke cable is stranded. Do I have a bogus part?

go to a bicycle store the have lots of cables and different thickness cables and you can buy just the cable and not the black outer housing unless you need it, thats where I got my choke cable, like said heat it up and pull it out, if you have a oxy acet torch then braze in the new one

Inner choke cable are all stranded. Least the three that I have are.

For the choke cable to last a lot longer, only one carbie needs to be hooked up to get the car started. I remove the (choke) link rod to the rear carbie, and just choke the front carbie.

Then, with only half the return spring pressure, you don't have to put your foot up on the dash to pull the choke cable, and it's a lot easier to half twist lock it on until the engine warms up.

No need to carry a peg to put behind the choke knob to keep it out, or sit a small coin on the flat between the choke knob and the dash, as we did as kids in our TR2's until we figured out a few short cuts.

I second the bike shift cable as a replacement, also setting it up for the front carb only. If you're really good at brazing, OK,but soldering works fine. After you get the old cable out, drill out the hole to the same size as the new cable so you can get an easy insert.Cut your bike cable to correct length & tin that end so it won't unravel.

Then, with only half the return spring pressure, you don't have to put your foot up on the dash to pull the choke cable,IMO, if it's that stiff with both chokes hooked up, there is something else wrong. I pulled the same cable every day for almost 20 years, still worked fine. I grip the knob between index & middle finger, then prop my thumb on the dash. Then a twist of the wrist pulls the choke out, and another locks it.

I've found that it's common for people to try stretching the spring between the jet glands, which makes the choke hard to operate (and also gives the jets a tendency to stick down, causing overly rich mixture even with the knob all the way in). Then some will shorten the return spring, to get the jet to come up, which makes the choke even stiffer.

Also worth noting that all those pivots in the choke linkage are supposed to be loosy-goosy. Substituting bolts for the pins, and pulling them up tight, is a mistake.

Pressing on the throttle while pulling the choke will also make it a bit easier.

Oh yeah, the jets are supposed to be smooth and shiny. Many aftermarket jets aren't smooth, and need to be polished before installation.
