Yeah, sorry about that! Life, family and house renovation are to blame, but I'll definitely be posting videos again soon - front heater refurb, new fuel pipes, more interior trim, and a steering box replacement are all coming up. Thanks.
Another interesting upload.them aed starter carbs,wot a pain on the series 2 daimler me dad used to have.even the jaguar dealer couldnt set them up right.the one on my old s type is electric using an otter switch.i need a new one of them,i have bypassed it for now.its a much better choke than the aed which worked off hot air.it still has issues with flooding tho.lookin forward to your next one.
This feature is a long term Rover item - my parents had a P4 Rover 75 cyclops version that had the fuel enrichment light activated by engine temperature. It had SU carburettors that enriched the fuel mixture instead reducing the air intake which is what a choke did.
Very true, the Cold Start lowers the SU carb jet so more fuel goes in. I hadn't thought about why Rover didn't call it a Choke - they were being more accurate.
Ah, thats interesting - there wasn't a return spring fitted when I took the original off, so I didn't even know there should be one. I wondered why the arm had two holes! Hmm, might need to reconsider what I do then - will consult the workshop manual or parts catalogue. Thanks for letting me know.
@@Mid-Century-Living no problem. The spring is the only means of getting the reserve pull lever to return home. There is a locating tab for the spring on the detachable cross member. Excellent explanation of the otter switch by the way. Later P5B's have the third hole for the choke warning light on the dash already in place but it is covered with the dash fabric just leaving the oil & ignition lights.
Good idea, I should have tried that. I was also thinking that the marking that says ‘B37C’ might be the temperature the switch closes in Celsius - would make sense that the coolant is just starting to warm up, so the cold start can be switched off.
It will OPEN when the engine is warm so won't work! The warning light will be on continously until the engine reaches operating temperature then it will go out.....unless you have found the elusive NO switch.
Hello, that’s not what the Instruction Manual says, nor the club forum. The Otter switch is Normally Open, and as the manual says “The appearance of the amber warning light marked ‘COLD START’ will remind you that the cold-start control is still out and should be pushed in at once.”
@@Mid-Century-Living just do a continuity check to see if you have been lucky and have acquired a NO switch. There are two types and they look identical. Obviously, the NO switch will close when hot and will complete the circuit. Personally, I prefer the simple system which leaves the amber light on until the cold start is pushed in to fast idle as determined by the Brycrest switch.
Hi Richard, seriously no problems. Unfortunately there is not a reliable system for cross matching part nos to get equivalents, it's normally the computer says no, when it doesn't know and in our areas there's a serious rareitis issue with these kinds of parts. So it pays if you have a part no to keep it.
I'm learning a lot about my car. Very informative.
Looking forward to a new upload. It's been a long time!

Thanks for the upload. I notice that the actuating arm on the new NOS reserve tap doesn't have a hole for the return spring.

can you test the otter switch by putting it in a pot of water on the stove with a thermometer and see what temperature it operates at?

EW makers mark, would it be Edmunds Walker ?
Hi there can you tell me what the part no of your Shock was?
I'm not sure but they were from J R Wadhams - if you look under the P5 section they'll have them listed.
@@Mid-Century-Living I use Wadhams quite a lot and yes I have seen them there, the point was I was trying to get an OE part no. But thanks anyway.
@@leoroverman4541 OK, apologies. They're on the car now, so not so easy to check I'm afraid.
