Choke

I have a new hook type choke knob (I wouldn't have believed how rare they are!). I got this after the original snapped. Unfortunately the cable was sawn off and so I only have the plastic knob and the metal shaft. I have got piece of bike brake cabe which will pass through the sheath but the question is how I should join the cable to the shaft, any ideas? Does anyone know how the original is joined?
 
The shaft is line drilled, the cable inserted for about 1 cm and then crimped.
You can do it (i did it myself) but it is rather tricky to drill the length of the shaft with a 2mm drill bit.
Note that if the shaft is shorter than normal (you say that it was sawn off) the choke warning light will stay on.
I also had this problem, and overcame it by cutting a suitable length of a shaft out of another choke knob (a round one that is very common) that has the same profile, line drilled it, fitted it over the cable to meet the shaft, crimped it, soldered to make a uniform joint and then filed it to remove the excess solder. It worked!
My alternative was to find another SC hooked choke cable, but i had not much luck with this.
 
With the high risk of a repeat failure resulting from a home repair and the PITA of replacing the cable again, wouldn't it be better to try and source a secondhand one from a breaking car on Fleabay? Alternatively does Jim at Red Hat Rovers in Huntingdon have any spare on the models he is breaking??
 
Martin, I feel your pain of a broken knob, I have just snapped mine in half this morning, I have poor feeling in my left hand, and I thought reduced grip, the choke knob stuck in, and half of it stayed in my hand, OOPS... :oops: Good job swambo was in the house because every adjective that shouldn't be used in polite company, was!
 
I got one from rover classics for mine.... not sure if it was new or 2nd hand as the cable was very long ( past the carb ) so i guess it's never been fitted to a car before PAE?

Worth a phone call. Dont think it was expensive...

I just might give them a ring, but I have a friend who used to have P6's and he states has a garage full of spares, so a stealthy visit with a handful of folding pictures of good Queen Bess the 2nd seems to be called for.... :mrgreen: (and maybe a trailer)
 
The thing that breaks them in my experience, is if you pull the choke out without a light throttle application. This leaves the knob to work the choke and throttle linkage which is heavy for any knob :wink:
They're getting old now and need all the help they can get :)
 
I got a replacement used knob and cable from Wins. I discovered the reason for mine being stiff, some muppet had shortened it and crimped the carb end ferrule too tight and it jammed the cable. AHA :idea: I will just remove the inner and insert my new one. Oh no I won't, the section the choke light sender bit thingumybob fits on is a different section :cry: , so I have to replace the outer and inner. If I ever got hold of the guy that designed the 3/4" retainer nut I will snap his pencils, had he had a career change from being a gynaecologist? Because undoing it through the speaker aperture with my big mitts is impossible. It's off to my local engineers tomorrow to slit an old 3/4" socket to slide over the cable and try and loosen the nut which appears to have been tightened by a gorilla. It would help if I could figure how the radio was held in but it has something holding it on the right side. Oh well it keeps me from being bored!!

You need Popeye's Pipe! (A quick look in the back of the WM and all should become clear....)
 
I know Harvey that's why I'm bodging an old socket. If I had 9" long ratcheting fingers with a locking facility it might help, evolution failed me again! :D (it's a long failure list)
 
New "easy pull" choke knob/cable fitted. I am not sure if if the choke warning light unit is in the right position, but at this time, too be honest, I don't care :oops: It can be sorted out at a later time. I have 'P6 kidney' from the ergonomically unfriendly seat adjuster digging into me whilst I wrestled with the fittings through the speaker aperture, and non functioning fingers in my left hand, but, on the upside it is fitted and the damn thing now starts without the use of Vise Grips. Hurrah!! :D
 
It only takes 5 minutes to undo the four nuts that hold the seat onto the runner mechanism & remove it. Saves your kidneys a lot of discomfort.
