I would like a locking choke cable that actually works as described.

I've bought two now that don't work. Well, not while the engine is running anyway. Fine with everything off but even at idle they seem to slowly untwist and snap back in. Very annoying indeed.

Anyone been able to find a locker that stays locked?

Concur!

I can't remember a time when I had one that worked correctly, particualarly on twins with twice the choke clock springs. I have to use a clothes line peg to hold it out.

Old Toyota Landcruiser ones are brilliant, but not really a choke.

On the old HJ75 (diesel) just pull the hand throttle know out all the way & twist, it would sit at about 100kph like a cheap cruise control!

Doesn't everyone have a clothes peg on their choke cable? I'm tempted to knock up a lever of some sort using a BMX hand brake lever or something.

Just don't lubricate the cable, they get stiff pretty quickly.

Oops, I've opened a can of worms with this one!

Now, where can I buy a polyoxybenzylmethylenglycolanhydride peg?

I've had one of the MKII S ones from Minis Plus in my car for a couple of years now and never had a problem with it.
Just pull it out and turn to lock it, start the engine and drive off. Cable dosen't move untill you turn it back to unlock it.

You're in luck!

I have a bag of NOS Cooper S pegs on my back line!

The dog has eaten some, but the rest seem ok...that is only if Megan isn't hanging clothes out.... in that case then I'm not allowed to touch them at all.

Sounds like a production defect, you could bring it back under warranty citing it doesn't work the same way as the rest of the choke cables :P

I'm going for originality here. Do you have any the correct faded shade of pastel BRG?

Actually, I have this idea of removing the knob, fitting it to a two speed pull switch, and connecting the cable to a hidden solenoid.

There goes the KISS principle...

The Morris Minor choke cable locks. When you set it up, you twist the inner cable before you clamp it at the carb. That rotational force keeps it held against a ratchet mechanism at the knob end (snigger!). You usually get 3 or 4 levels (clicks), where you have to twist the knob slightly to release it.

They're sometimes discarded because the inners get ratty and folks aren't keen or clever enough to solder in a new one.

Got to be worth a try.

Thanks
