Mk1 PI Choke cables

[Jason]

You know how it is, you see something that's wrong and you just have to fix it, no matter that it's not that important but you just can't rest!
So, Mk1 PIs has a twin wire choke cable and a round choke knob, one wire goes to the excess fuel lever on the metering unit, the other to the throttle - it's not really a choke at all but it's used in the same way. You can get away with just having a single wire connected to the metering unit and when you start the car you just give a little pressure on the throttle pedal.
Anyhoo - I need a twin wire cable BUT they aren't available anymore so what else fits? There aren't many cables with the correct knob and two wires but a Stag cable comes close as does a TR6 etc.

So I have a few questions

<li>Will a Stag cable fit and work?
What have other Mk1 owners managed to make fit and work?
What are the critical dimensions?
</li> </ul>

If you have an original knob (Ow err missus), these guys might be able to replace the cables. They did a similar execise on a Triumph 2000 MkII with a broken cable.

a mk2 knob will pop off the dashboard end - have you tried to see if a mk1 knob will pop back on?  There are two different mk2 cables (early and late) - both the same to the mu but early longer than late at the inlet end

[Jason]

I've got the remnants of what I think is a Mk2 cable - the dash end with the Y piece in, I've also got a standard Mk2 non-PI dash end and knob that is not connected to anything in the engine bay at the moment - I haven't examined it to see if the knob is detachable.

I will resist the temptation for a knob gag.........must.....resist.......

My choke cable knob came off and just replaced with a new (but old) knob with a new hole drilled and screw inserted.Can hardly see the screw and it works till can fix properly

I think we bought a new Stag one. I have an idea it just needed a bit shortening or something... Barry might remember.

[Jason]

Thanks Caroline, can you ask him as the Stag ones I;ve seen are like £45 and I;d hate to spend that on the wrong think!

Speedycables seem to be technically challenged at the moment, their web site is defunct and their email address is bounces. I've tried the phone but the don't work Friday afternoons!

Are you saying that's what you paid or that's what's available?

[Fuzzy Harris]

I don`t think the mk2 is long enough i bought a new one for my mk1 pi and it didn`t reach, something to do with how the cables run around the heater i think ? i`m tryin to rack my brain as to what i fitted, if i remember i`ll post it.

[Jason]

Thanks Phil, I don't even know what the correct length should be - might get a piece of string out and measure it :-)

[AlanChatterton]

ah............. yes, the £10 was a MKII Pi cable, forgot yours was a MKI PI!!

oopps!

[Barry Acclaim Guru]

We did buy a stag one for the mk2, but we are still using the origional one for the mk1.

sorry not much help here.

[Jason]

Is there any obvious difference between the two Barry?

[Fuzzy Harris]

I`m sure the stag  one isn`t long enough on a mk1, i will stand to be corrected, i`m sure i used a tr6 cable on my mk1 pi.

[Jason]

and how's your knob look?

[Fuzzy Harris]

The rash is clearing up thanks !!

[Jason]

I'll line 'em up you knock 'em down :-)

Does your choke knob look OK, that is the knob on the end of your choke cable that you see from the driver's seat (I nearly said cockpit then but that would be too much of a gift for you)

[Fuzzy Harris]

Cant remember mate, i`ve sold the pi now, damn i could have said that when i pulled me knob out she coughed and spluttered till i pushed it all the way in !! go on ban me lol.

[thescrapman]

I wish to protest in the strongest terms about the filth you 2 are posting on here.

;D

[Richard B]

You two are taking the PIss     :D

[Jason]

I apologise for the filth but what is the politicaly correct term for a choke knob? On second thoughts I'll get me coat now

fuel enrichment cable activation handle?  ;D

[Jason]

Catchy

UPDATE on the MK1 PI fuel enrichment cable activation handle quest.

So far I have bought a Stag cable and a suspected Mk1 PI cable, both look identical.

I'm working blind here as my only reference is a Mk1 2000 dash knob - ie I know what one end should look like!

What I really need is a couple of photos and some dimensions. How long are the two wires? How long are the two outer cables? Is it a conventional multi-core twisted wires type cable or a solid single strand (like a Herald heater cable)?

Speedy Cables don't respond to emails or contact via their website, I haven't yet found a time that they answer their phone but I'll keep trying - as I have the twin cable housing and the warning light switches, handles etc I should be able to have one made - at what price I don't know.

The car will not start without choke in the morning, at other times it's a struggle so this is a bit of a pain. The interior is so good I don't really want to compromise on what fuel enrichment cable activation handle is showing on the dash.

Wow, I got through all that without any knob gags :-)
