TR6 TR6 Choke cable adjustment?

I have an issue with the choke cable control on my 73 TR6. I can pull it out and turn it clockwise to lock it and warm up the engine. When I start to drive it away it will release and push it's self in which causes an embarassing sputter or stall. It is very difficult to hold it out while trying to shift.

Is there any adjustment on the choke control cable?
 
Not really an adjustment, but it may be repairable. At least some of them have a brass blade that catches the notches in the shaft, and the brass wears out. I was able to disassemble and replace the blade (it's just a semi-circular piece of flat brass).

OTOH I understand this was a common problem even when new ... somewhere I have a genuine ST clothespin (courtesy Jonmac) to clip on the choke cable shaft

Tell ya what, Mabbott. Show up at one of the Cape Cod British Car Club, New England Triumph or British Motor Cars of New England event and we'll fix that for ya!
 
If you don't get a chance to take Paul up on his offer, you might want to check the detent ball that engages a notch on the fast idle cam. It might be gunked up and not finding a home in the notch in the cam.
The detent ball should engage the notch at around 1100-1200 rpms.
 
Thanks guys, I'll try the suggestions. I did think of the close pin / temporary spacer trick.

Paul, thank you for the offer. If it isn't fixed by then, I'll look you up. I did join the CCBCC and will try to make some events.
