had an evening out-n-about in the VDP, picked up mum from an appointment and took her to a place-that-serves-nice-food with my brother for an occasion :)

24 hours 7 days if it's the Brick Lane Bakery.

A decent spot if you are ever out late in London - just round the corner from Shoreditch High Street Station and known by every cabby. Do filled beigels too. 😋

Salt beef beigel is my favourite 😋

had an evening out with REV today :) 

IMG_4299.jpeg.3676c1f37cd6eb61e544dabc64650a2d.jpeg

my brother had another card game thing he was eager to try out so I got called in as a 3rd player, traffic was a bit gnarly so it was via the back roads of the city square mile around bishops gate (I confused a whole bunch of pub crowds in these narrow streets LOL) and up via southwark bridge

IMG_4304.jpeg.0869e1b757d589f45cb97d20eaa3c8f7.jpeg

they take a while these games, but eventually home again, back via my more normal route over tower bridge

IMG_4308.jpeg.b8ac7b04dd148ce7f7171a84291fccac.jpeg

I have noticed REV's idle is still AWOL, it will sometimes hang around for a few 10's of seconds before dying off, theres bit of extra going "TUC!" sometimes at light throttle but otherwise idle issue aside, still performing fine still, its a bit amusing the last time I did a big epic drive up the M40 & Down again, I also lost my idle!, until @Zelandeth worked magic fingers on the carburettor, the only thing outwardly found at fault at that point in time was a failed float, so dont know if the replacement itself has gone bad or was/is another issue at play (thats come back again?)

Hmm.  It's not impossible the float has failed again, no idea if it's something these carbs are prone to.

Would be useful to know whether the mixture is going lean or weak when the idle fails as that would help point at a float issue or possibly a bit of gunk getting in somewhere again.  I can't remember off the top of my head - you do have a filter in the fuel supply line don't you?

whats the best way of knowing if its going lean or weak? it appears to just petter out, ie it will slow down until it stops running, like if someone was screwing in the idle speed adjustment screw until the engine came to a halt (ill try and make a recording when im next out and about)

I do have a fuel filter inline at the fuel tank. which I recall last time i checked it looked clear/clean

 

tho its worth mentioning a few weeks ago back after she had sat a few weeks more then she normally does she had an issue with randomly coughing and spluttering to a halt at speed (30-50Mph) after which where it would idle, and respond to the accelerator pump but the main circuit seemed to be upset/not-working properly, turning the engine off and restarting it would clear it for a brief amount of time, sticking my hand over the carb at Lots-of-revs a few times appears to have cleared it, (See recent 200 mile trip up-n-down the M40 which was done without issue) but maybe its now sucked some crap into the idle circuits instead...

Check the filter flow direction is correct, l have found them fitted the wrong way and look clean with all the crap hidden inside.

I've bought a couple of motors from decent shiters and one of the had the fuel filter accidentally fitted the wrong way. It split on my journey home and pissed fuel everywhere. Definitely one to check!

well I always knew they where directional, but I always figured it was for flow reasons, ie that they might not  flow/filter properly if fitted the wrong way around, but I did wonder what the exact mechanisms at play was, so @Snake Charmer comment that is interesting indeed, the "filling up with crap out of sight" was not an angle I had thought about before hand

 

I am pretty sure REV's are the right way around, but ill try and double check next time I have my head down there :)

Add fuel - apply a bit of choke and see if it picks up.  If it does you're suffering from a lack of fuel.  

If it was stalling out because it was too rich I'd expect you to need quite a lot of throttle to restart the engine and noticeable black smoke though.

Worth just grabbing a screwdriver and making sure the screws holding the lid on the carb haven't worked loose though as that will introduce an air leak into the idle circuit - and I swear mine keep undoing themselves (guessing the spring washers aren't as springy as they once were) as I've definitely had to tighten them more times than the carb lid has been off!  Worth checking the carb isn't loose on the manifold while you're in there.

for what its worth if I crack the throttle open a touch, it will keep "idling" just fine, it only gradually dies off over a period of 5-20 seconds if I keep the throttle closed/hands off the twist grip

yeah Ill double check that! I do check for it fairly often, because I did once (back with the failed float) find them loose, tho they have not tried to loosen themselves again so far...

 

I also need to poke Haflinger-Technik and see what general supply of spare carb parts is "locally"

Same. Just assumed it was about different layers of filter media.

Well look what's turned up on eBay today...

Not sure about the price though! 🤐

Invacar 1975 Cobra 500 Blue | eBay UK

Oh its "Only" £5000 on eBay LOL, its currently also C&C for £10K LOL, here are my thoughts on it from the recent pages of the eBay Tat thread

21 hours ago, LightBulbFun said:

the sad thing is also the over-restoration which JPA268N has had, which as I understand was "all fur coat and no nickers", not just in the sad things done to the mould lines that are some of the fine details that differentiate an AC Model 70 from an Invacar Model 70, the wheels and shit number plates, shit headlights and shit mirrors

but on a more serious general matter, beyond just my rivet counting/personal taste matters.

in the past someone I know did go to look at buying that one back when the original person who over-restored it and converted it to steering wheel control, was selling it, and apparently some bits in the steering wheel conversation where done in a dangerous manner that caused one person who did briefly buy the car, to send it back! 

I cant speak of the exact details myself as I have not seen the car in person/and its been a while since I last discussed it with others in the know,, but there are certainly visible details that the restoration was done without all that much understanding/or care for the fine details, take for example the rubber flooring which was replaced, notice they have it with the rubber lines going lengthways

1975-ac-cobra-69ea424caf6af.webp.5d66ddc7345358db4c929b893bee43ef.webp

rather then horizontally across the car from door to door, its meant to be horizontally across the car so any water that happens to pool, can drain out the doors and provide and I think you would want it horizontally also to provide good grip against someone putting their feet down against it

so I would certainly recommend any prospecting buyer to go in with their eyes wide open and go over the vehicle with a fine tooth comb...

(im glad to see at least the original handle bar hardware survives with the car so it can be restored back to original configuration, it was not always a steerring wheel car, sadly it was converted to steering wheel, by the person who over-restored it, for all of the 500 miles he actually did with the thing, sadly its not the last time he did something like this VES108S/XEV88S was a very rare single handed tiller control machine, which got converted to handle bars and then sold! like FFS,, I could understand changing the control scheme to suit if you where going to seriously use the vehicle, but if its just going to sit around/not get used and just get sold, leave it alone...)

 

its certainly not a £10K car by any stretch of the imagination!

Probably not, except maybe with a 2x4". 

Shaldon pricing for you. Cross the bridge and everything is 3x more expensive!

if you can get the price down to a more sane level, buy it, and least stick a proper set of retroreflective plates & wheels on it,  (and converting it back to handle bars) I am all for that!

also I noticed theres an actual video of it being driven in the eBay advert my first thoughts where "oh cool a video of it in action" then seconds later "oh fuck me he actually calls it a Cobra..."

I thought he just put Cobra in the title for click-bait reasons... (or on C&C that its listed as that since theres no "Model 70" option under "AC")

had a fair day out in REV today, to attend the Anual general meeting of the Routemasters Owners and operators association, it had been almost 20 years since I went to one last time, and this time it was at the London Transport Museum Acton Depot where they gave a free tour (more just let us loose :) ) traffic was quite gnarly both ways (A40 was quite buggered in particular), & REV's idle completely left the chat, tho i found by opening the choke a bit i could keep her ticking over, but I managed to get there and back without issue otherwise :) 

IMG_4313.jpeg.110ebeb886eb279cdf18607b9b75d366.jpeg

heres a bunch of photos in no particular order

CUC192 was fun to see, theres a fun website that has a list of all of London Transports Non-bus vehicles, all the support vehicles, and I had read about this one on there :) I think this was the website https://www.ltsv.com/

FRM1, the rear-engined-front-entrance Routemaster Prototype, I have often wondered how things might of turned out if the built a load of these instead of the unsuitable DMS's

IMG_4318.jpeg.f4c64cc9ed92caf02da5cbef94c96ace.jpeg

RM2, the second Routemaster Prototype, apparently it had a FTP at RM70 and its been worked on since, not sure what went wrong but I see evidence of recent work on the cooling system I think

IMG_4323.jpeg.0b932ffa1b3baa2c2a90d62bde0ef843.jpeg

the chassis of something very old, and curiously petrol-electric by the look of things?

a Leyland Cub, was quite fascinating to see one of these in person, and see all the details I had not noticed before now, like the Central mounted fog lamp, and big filler cap

I also managed to find the Wagon the museum keeps all its spare fluorescent tubes/lightbulbs in, how I would love have a good rummage through it and take home a few souvenirs!

they had also removed all the tubes from the 1972 stock for some reason

IMG_4361.jpeg.ea6597cc39da6899a11a4f0c4ab2c8f8.jpeg

but can you spot the odd one out?

IMG_4362.jpeg.e32308562b8e9374ab6c796194503522.jpeg

yeah see the one without pins? I really-really-really want to know what thats doing there and where thats come form, because thats an American high-output fluorescent tube (different from the American Slimline tubes found in 1990's Trasnmatic lighting that found its way into many 1990's buses and refurbished RMLs), seeing that tube there is like seeing a Row of FX4's at a taxi rank and randomly in the middle of it is a full New York spec/Livery checker cab in the middle!

 

finally a couple shots of REV outside the depot :)

then headed home, got some petrol, 44Mpg, which given the horrible traffic REV has had to slog through since last fill up, ill take that!

IMG_4371.jpeg.c873e0103bb384ef83f3b842fcb51593.jpeg

stopped via the bakery

IMG_4373.jpeg.197b7ffa67de779a3384702ab46911c8.jpeg

then finally home :)

IMG_4378.jpeg.49dc6d9e4a7bbe31fc8e56dc5a93cead.jpeg

all in all a good day, if not a bit longer then I expected! was lots of fun being allowed to just run around the depot :)

heres a video of it playing up, only way I could keep the engine ticking over, was via a fair application of choke, I checked for loose things on the exterior of the carb and nothing seemed loose, but I have not yet gone spraying things with break cleaner or the such like to try and see if theres an air leak somewhere...

for what its worth I noticed that the left hand connection of the exhaust to the intake manifold, was much cooler then one on the right side, I dont know if this means anything but given the difference i thought i'd note it!

Acton shed is so much better than the actual LT museum mainly because it's not set out as a museum at all. It's kind of the overflow storage for the museum. It's usually only open to the public a couple of times a year. 

Here's a few from some of my previous visits. 

This is Mrs Yoss being taught how to not crash Underground trains. 

20160925_113450.jpg.f5351f9709adf78360fb549fc1321969.jpg

Very art deco poster. 

20160925_121443.jpg.49c115742afe252ede00452f9946a389.jpg

 

A row of RM grilles, but proper original grilles with stainless trim and badges that always got stolen. And one can only imagine what is in those cabinets. 

IMAG0045.jpg.3d69736624a33837c153a90454a80923.jpg

 

Random furniture. 

IMAG0049.jpg.a84def1a61a97763640b708f8750a89c.jpg

 

A row of engines all palleted up ready to go should one of the museums fleet of buses need them. 

IMAG0037.jpg.e81c80803d0556188b1058de5fb0f48e.jpg

 

Some fantastic models in there too. This is a cut away of an Underground station, I forget which one. Shows how all the passenger and train tunnels link together

IMAG0041.jpg.9f006e851721a4dc8ad0907ea677051d.jpg

 

And this is a very small scale model of Aldenham works. If you look carefully you can see some tiny buses which show how absolutely massive the place was. It appears to be the size of a small town.

Nothing to lose by replacing the fuel filter to see if there is any improvement- cheap and cheerful fix. 😊 Just check the air filter too for any debris. Sounds like crud in the carb - but try the easy stuff first.

Marathon tomorrow probably why London was busy getting stuff done before the city closes down in the morning.
