Evening, The good lady has just bought a Mk1 Fiesta from Morgs (Charlatan1) on here and it's come with a pair of Weber 36 DCsomethingorother twin carbs which were part of a genuine Ford Motorsport kit for the 1.1 Fiestas. It strikes me as crazy to have a pair of 36s on an 1100 but chuffing cool at the same time. Anyway, they need some love in the form of a new diaphragm thing on one of the to stop the fuel falling onto the exhaust.. I promise they will go back on, but in the meantime, I have a stock carb and manifold (first person to say 'fanny mould' gets a slap with the same wet fish that was used on the last person to say 'Hell Frauds' ;D ) that I can throw on just to get the thing moving under its own internal combustion. The problem is, I know nothing about Fords. Or about Carbs. And it's my girlfriend's. And she thinks I'm well good at cars. So with the lack of a Haynes at the moment, can you please help me identify a couple bits? Petrol in the brass one, but what's the plastic one for?  That correct? How should the throttle cable actually attach?  And this?  Thanks in advance. You're helping me get boyfriend points ;D |

'vac advance' is the acclelerator pump. Spade connector appears to be a fuel stop solenoid. Choke is correct, as is throttle, but as I don't know Fords I don't know what that plastic pipe is unless its a fuel return?

Hmm. Looks like my guesswork failed a bit there then. When you say accelerator pump, do you mean the thing with the diaphragm in it, or the little tube below it that I was trying to point at?

that little pipe under is vac advance i reaconl, I think that plastic pipe is a breather/vent? don't think older fiestas have a return pipe. the old escorts 1+2 had a breather pipe which just hung down below the carb.....sort of an overflow maybe? someone here will remember.

Oh, I didn't see a little pipe. I imagine that yes, the little pipe will be vacumn. Any idea what carb it is? I may have a haynes manual that covers it but only just..  |

The markings on the carb below the question marks in the first picture are..
"Ford"
"77BFKHA"
"1ED"
If you do have anything, that would be awesome. If not, I'm feeling a bit pathetic about asking about such a simple looking carb so I may have a go at boshing it on anyway and seeing what fits!

Cool carbs. The extra pipe at the top is a fuel return. I've always just blocked them off and they work no problems. If you don't have a vacuum advance on your distributor you should block the bottom pipe off too. The spade connector is a fuel pre-heater, but it's worth checking as it might be a cut-off like someone said.

It essentially means I can just wang it on and start earning boyfriend points. Though she REALLY wants to keep the Webers on there. She's got taste! Thanks for that. I'll give it a bash tonight

the lower spec/engine fiestas never had a fuel return. i'll check my haynes tonight to see if it says, otherwise, sign up to www.fiesta-mk1.co.uk and ask on there, you'll get an absolute answer. p.s. don't keep that on for too long, its an awful ford vv carb  |

Variable Venturi, yeah? It won't be on for long, just long enough that the leaky weber can be sorted and then we're back on track for having a car that sounds as good as it looks! Going to have a bash at the swap tonight so wish me luck... |

Where is the Weber leaking? There's no diaphragm on a DCOE, the throttle pump is a plunger. Have you checked the floats are shutting the fuel off? They overflow and pour fuel down the bores when the fuel doesn't shut off. Take the top cap off and the floats come off with it and dangle down like a pair of hollow brass knackers. Or black plastic knackers if you've got later ones. If you put your lips over the fuel union and blow you should hear it hiss out the other side. Lift the floats up and it should completely cut off. If it doesn't then you need to replace the needle valve jet. If it does then check the float height. Where the tab *just* touches the needle valve ball it should measure 12mm between the top of the float and the case. www.webcon.co.uk/Downloads/DCOE%20float%20height%20setting.pdf |

It's a pair of Weber 32 DCNVAs. I know nothing of them, other than that one is leaking from behind a square plate on the side. I assumed it to be a diaphragm underneath but I haven't looked properly yet. Just looked on google images. Pictures are somewhat lacking, but I reckon the fooked bit is the sqaure thing in the top right of this pic. It's on the edge between the two carbs so I can't get to it with a screwdriver until I take them off to find out. Can you tell I don't do carbs? ;D  |

if you can get a proper rebuild kit like the above then do that, new gaskets etc. and new diaphragm. should sort it easy then carbs aren't too difficult, its figuring out what does what that makes them awkward, good luck, let us know how you get on, and get some piccies up of the fiesta |

Ah right, it's nothing like a DCOE at all, disregard all of that.
Like kee said, if you just get a pair of kits like that it's pretty straightforward to fit.

Petrol in is correct
Plastic one is fuel overflow. They just had a nylon type black hose which dropped down the side of engine to exit excess fuel (away from heat)
Throttle cable is correct. Ford used a cable with a half round plastic cable end with a hole in it. You just push is on the ball joint and a clip slides over it to hold it on.
Choke cable correct. Think the bracket on corner of carb is the clamp
Spade connector is for anti dieseling valve or fuel shut off as has been said.
Vacuum is small pipe as been said
The square bit is accelerator pump and has a diaphragm in it to squirt juice in when accelerating.
Simple trouble free carb unlike the VV carb used on larger engines
Edit to say, yes the bracket on corner is cable clamp for choke, it uses a special clip (most fords used it on choke cables) which hooks through one slot, clamps cable and pushes into other slot to lock

Cheers The anti dieseling shut off valve thing.. That means it won't start unless it's got 12 volts, yes? I hope so because I tried it without it connected and not a hint of it catching. I couldn't see a corresponding dangly wire anywhere, but I'll look again, and if I can't find one, I'll run something from the ignition. I'm so sorry about this. It was me starting this thread that made me start the 'daft question amnesty' thread.. |

I think from memory that you need a live to the fuel shut off. I seem to recall it is a solonoid which is pulled back by ignition and then shuts when ignition is turned off. ie when you switch off.
It was designed to stop running on when you turned off. Early Fiestas suffered from that as well as some other Fords.

Ben, I don't remember there being a wire for the shut off solenoid when I helped to get it up and running on the twin carbs. Normally I'd suggest tapping a wire onto the + terminal on the coil but yours runs ballast ignition so the + only gets 12v when the starter's turning, the rest of the time it's only 6v-ish.
