For those contemplating fitting one of these excellent carbies, I've attached an exploded diagram and the (my) english translation of the component list.

Occasionally the link between the main throttle and choke levers is missing but so long as the return springs are present to hold the choke butterfly open, it is not a major drama.

The link is used to open the main butterfly slightly when the choke is manually operated by the choke cable. If you don't use the choke - I don't but then I live in a relatively warm climate - then the missing rod is not a problem. If you use the choke to start in cold weather and the rod is missing, just push the accelerator pedal a little when starting and all will be well. I've attached before/after photos to demonstrate what I mean.

Happy bambino-ing,
Chris

Forgot the other attachments - sorry.

Thanks very much for posting this Chris, it'll definitely come in useful when mine arrives.

Just out of interest, how do you clean up your parts? (Car parts that is!) On your engine build thread, you've got the parts looking like new.

I have a small soda/bead blasting cabinet for the large parts.
Also a 1:1 mixture of petrol and methylated spirits (ethyl alcohol) and a used toothbrush works well to shift stubborn dirt and grime in difficult to get at areas followed by a sharp spray of aerosol degreaser.
Some of the larger parts can also be cleaned using a wirewheel on a low speed drill.
Carby internals are cleaned with the usual carby cleaner.

It takes time, energy and dedication - difficult when the sun is shining and the beach is beckoning

Plus I cheat - some of the engine parts were new.

As for my parts, they are getting on a bit now, but are still quite functional

Chris

I keep seriously thinking about getting a small blasting cabinet now that I've finished setting up my man cave. I can see it getting used quite a bit when I get a 500, or on bits for my Dad's MGB.

Living inland in Enland I certainly don't have a beach to distract me, or the sun for that matter!

Throttle linkage setup

Once mounted on the manifold, connection is very straight forward. I retained the standard throttle cable setup to the top of the left-hand side tinware and joined from that point to the carby using a standard adjustable link. In order to clear the carby body, I gently bent the centre part of the link about 30 degrees.
On my car, the choke cable is not connected as in my climate I don't need it to start the car. It looks to be a simple matter to fit the cable if necessary.
One final point - these carbies can be configured so that the actuating links are on either side of the carby body. It would be worth your while making sure that the connections face the rear of the car prior to mounting it on the manifold. Swapping them over is not a major problem.
Regards,
Chris

Hi Folks;
A good way of getting items cleaned, especially delicate alloy carb parts, is have them 'VAPOUR BLASTED'--this system uses very small glass beads (120/200 micron)suspended in water and blasted at about (so I believe) 60 psi. It does a beautiful job of cleaning, without damaging 'gasketed' surfaces. I believe it is a relatively new system (I'm lucky in that I have a company with the equipment just outside Colchester, in Essex--about 30 miles from my house)--I found this company advertised on Google. It is also known as Aqua Blasting or Wet Blasting.

Thanks very much for the photos Chris. Since you kept the original fan tinware and didn't go for an Abarth fan cover, how did you blank off the original air filter for the carb?

Not very well, I'm afraid - this is probably the ugliest part of the rebuild.

I cut the old air filter chamber off and had a mate weld a cover over the hole. It didn't turn out too badly, but at some stage I might redo it. I still have the old filter cylinder in case I want to reverse what I did.

Chris

I have done a couple of those covers for different carb set ups. One retaining the bracket for the throttle pivot mechanism (FZD carb) then another totaly stripped with that bracket removed (side draught twin choke Solex).
Like you Chris I did not like popping on a cap so I ground it all flush the welded in a plate so you just get a smooth flat top . I think that it looks better and thought that it might be better in terms of cooling air in that there might be less turbulence more like the "snail" housing on the German Bambino

Thanks Chris and Toshi. I'd thought about getting an alloy fan cover, but then it occurred to me I'd need to re-attach the throttle pivot. Your way will definitely save me some money and gives me an excuse to use my MIG welder.

Chris, where did you get the adjustable link?

Cheers, Matt

The local carburettor and tuning place - they come in various lengths and are not expensive.
Chris

Thanks Chris, I found these linkage bars on the Eurocarb website which should hopefully do the job:

Hi Matthew,

I've fabricated a new throttle lever for the FZD and also made up a throttle Link out of 6mm threaded rod and 6mm ball joints. I'll cut the thread to the right length and bend it so it has a straight pull from the throttle crank to the throttle lever.

Very nice.

The link that I bought has different threads on each end so the length can be easily adjusted, but having fitted it, I've not touched it since.

Chris

Hi Chris

thanks.

The ball joints at both ends have 12mm of 6mm thread so the rod can be adjusted by about 12mm to leave enough thread in the ball joint for security. When I pop across to Matthews to fit it we'll let you know how well (or otherwise) it works.

Richard (Matts Dad)

Hi Matt's Dad;
When you see Matt next, please give him my regards, I will be seeing him over the Christmas hols. He and I regularly communicate regarding a number of details as we are basically doing the same sort of project--but isn't it great when the son has to rely on the Dad to sort out a problem!!

I'm trying to work out what filter to attach to mine. It came with a trumpet, but it's open without any gauze or filter on it.

The other options are a trumpet with gauze on from Ricambi Sport:


Or the RamFlo filter from Dellorto.com:


I think I prefer the look of the trumpet, but I wasn't sure if the gauze would be enough. Living in the UK, it's not a dusty environment, so I was wondering if I can get away with just having the gauze. It will stop any larger bits of detritus (pebbles, leaves, household pets, small children, etc) getting sucked into the carb, but ideally do I need a filter?
