Do you actually need to use choke on these? Or a few squirts of the accelerator to prime up the intake and go like on Webbers/etc, unless really really cold.

I've found with TPA that the choke is on full for the initial start, backed off after a couple of seconds to about 1/2 mainly to keep the idle speed up a bit, then off after about 2 minutes/~80C on the temperature gauge.  Otherwise she will tend to spit back through the intake the moment you even look at the throttle.

Subsequent starts in the day unless I've left the car for many hours I don't even look at the choke.

I get the impression that these carbs tend to run these engines on the lean side, especially a low RPMs.  Being coupled to a stinking heavy flywheel probably doesn't help low speed responsiveness either.

I for one can't wait to see this on the road and the beginnings of the actual 'Touring Adventures of Lbf', 

Over the past couple of years, I've read shit loads and now know so much about the theory of inco-cars. Seeing one on the road, in daily use doing ordinary 'an car' things and particularly other proper, long distance adventures is something I'm really looking forward to reading about.

Where are you planning on driving it to first?

We could all meet you there...

It might be yer actual automotive fun!

You and me both! I have been itching to have her back for a fair while now  

once I have done a number of smaller trips around the local area and London to build up some confidence in myself and assert how reliable things are, Im aiming for the FoD to be my first "big" trip with REV, ideally id of liked to have also been able to make shitefest with REV but thats only 2 months away and is a 6 hour drive from here! which I dont think will be enough time for me to get comfortable with such a trip sadly

otherwise, I have a number of lighting related bits and bobs with various shitters which I want to finally pickup, primarily the 2 special 1963 Philips 40W 4ft T12 Woods glass ultraviolet tubes which Skizzer has very kindly been looking after for me since Jan 2020, that I really want to pickup, but I do still need to test what the maximum length of fluorescent tube I can fit into a Model 70 is, I am hoping I can at least get a few 4ft's in diagonally in the wheel chair space, 5fts would be optimal, but I think thats pushing it

I also have some vintage computers in my name with a friend in the Netherlands, so ill be tackling that at some point in time. but that will obviously be a fair ways down the line given that involves literally driving to another country which is no small task, but at least I wont have to worry about any Right hand drive car in a left Left hand drive country issues

Update.

 

 

Runs somewhat like it should. Probably.

As for carb/gasket concerns, dont ask. At all.

Suffice to say I can take the damn thing apart in the dark, blundfold, drunk whilst actually in a nother room. The 'bits-a' carb ended up being cannibalised  as well due to a reluctant jet. Etc etc.

 

Anyway.

[red5]

Not shown - the gaskets. The fuel spraying, the blow-backs. The 17th time taking the damn thing off dripping fuel onto hot exhaust whilst gouging head on engine cover stay.

Woo! very pleased to see an update on REV I have been missing her a great deal! I cant believe its been 4 months since I sent her off!

glad to see she is running well for the first time in probably over 20 years!

and I do apologies for the all the fight and injuries that happened!

 

mind to be fair to REV if some random bloke you had never met before suddenly started rummaging around in your behind, you too probably would also put up a fight LOL

 

hopefully its relatively plain sailing from here on out! and once again many thanks for everything you have done and are doing to get REV sorted for me, its as always seriously appreciated  

[red5]

Whilst I'm there...

Not entirely sure who said the fuel pump didn't?

[red5]

Might actually help if it was on 'not upside down'.  So let's try that. 

Stripped and checked whilst it was off.  Removed debris from diaphragm and outlet. 

[red5]

It's been apart and re-assembled upside down.  It does this- 

 

Cleaned, re-aligned and re-assembled.

Tested for the suction before refitting, because the lower stud is a shite to get to without removing some bits.

So off they came with no snappage. Win. 

Suction is ok.

Not shown- poking 'something' into crankcase to see if the drive for the plunger operates.  It does. 

Checked pre-load on pump -close enough. 👍

[red5]

Fuel pipe from the pump was run along back of cowling lower section, then through a couple of 90's. Short ones. Too short. 

Pipe removed, re-routed for testing.

External fuel can is mainly so I don't have to look at the arrangement at the front....

[red5]

There is a metal feed pipe across rear of engine/mount - removed, check for the blockage mate, cleaned for refitting. 

Then whilst waiting for fuel wired back and painted.  

 

[red5]

It's like watching paint dry...literally

However...

Et voila 

It's running off its own pump.

so forgive me if im reading this wrong, but, the reason the mechanical fuel pump was not working was because someone installed it upside down?!

thats hilarious if so LOL

very awesome to see the mechanical fuel pump is working once more  

we should be able to rip out the cheap-n-nasty electric fuel pump I installed to get her moving and revert everything back to stock now

if your curious (probably not but ill ramble on about it anyways!)

that fuel line would of originally ran all the way to the front of the vehicle, it seems like in service as the metal pipes failed the repair shops would just cut them short and re-run the majority length in normal plastic/rubber fuel hose, as seen with REV etc

which is interesting because all Mark A's and early Mark B's all had plastic fuel lines from the factory, it was only with later Mark B's from about June 1975 onwards did they switch to metal fuel lines

I wonder what the reasoning for the switch was!

[red5]

If you want the fuel pump I'll go and get it out of the bin in the morning. Its still fucking noisy in a bin with no power!

Might have removed half of the spaghetti junction impression already. 

And fixed the fuel gauge. Because it was really annoying me. 

I'll fill the tank and see if it actually shows an 'accurate' reading as well as just moving a bit.

[red5]

And refitted the ignition barrel so it doesn't flop about.

Only half was upside down. The plunger body part, air vents pointing upwards. Also full of crap in general behind the diaphragm.

yeah if you could fish it out that would be good, it might be a cheap and nasty POS, but its always good to have on hand for emergencies!  

and awesome to hear things have been tidied up and the fuel gauge is showing signs of working! I was worried about that being a PITA because of the miss-matched fuel sender, but glad to hear it sounds like it works

@red5What's the latest? Itching to see this thing back on the queen's king's highway with a fresh bill of health and Dez looking like the cat that got the cream once again.

Update - 

Carb still leaks, but functions.

Routing cable from throttle to carb.

 

Engine tune - points gap double what it should be, distributor seized in place - yay   

16" in old money, or 0.4mm (was 0.8mm).

Timing spot on.

Awesome! to see REV getting some more TLC! I very much appreciate you taking time out to check the ignition side of things out, thats not something I had not yet had the opportunity to  check that out yet in detail yet, apart when we fitted new spark plugs at the FoD, (she had a miss matched set before hand!), and  an attempt to clean the points when she had a round of refusing to start at the FoD, tracked that issue down to a fuse needing a wiggle, so we did not touch the gap at that point (pun not intended!)

and thats good to know about her distributor being sized, I had feared and wondered about that! because its seized on @Zelandeth's and @dollywobbler's Engine's too, so I had wondered about REV's, again never got the chance to investigate it myself, so its good to know what the situation is there, I dont think anyone has been able to free it off either, is that something you have managed to do wtih REV, or was it an understandable case of timing is good so leave well alone?

I am curious on the timing front, if you managed to take measurements,  how does REV's timing line up with TPA's? Zel's measurements can be read here  https://autoshite.com/topic/29443-zels-motoring-adventuresmerc-renault-vw-ac-model-70-a-sinclair-c5-2304-renault-issues-de-mossed-camper-aimless-invacar-wandering/page/141/?tab=comments#comment-2497157

Partially freed it, enough to wind timing back 12deg !

I'd post video but not sure how do these days. Or CBA to look ..

[red5]

Currently set at 4deg btdc dynamic for those of a interested nature.

Just curious, (and forgive me if I am reading things wrong!) if you wound it back 12 degrees, does that mean she was 16 degrees advanced beforehand, and you reset her back to 4 degrees advanced?

was that done because she was pinking/running rough with too much advanced, or is this just a case of setting things back to default while you sort out everything else?

Awesome seriously Awesome to see REV on the move again!  (and the CVT sounds like its doing its job quite well which I am really pleased about! as because I have never been able to get REV up to speed I have never been able to assess how well that system was functioning)

 

[red5]

How fast did you go previously?
