    Unfortunately this evening I pulled the Carburettors out and rotated them 180 degrees don't get me wrong they are set up just as they are shown on the instruction manuel....I think left hand drives must have the throttle cable coming out the right hand side of the engine.
    The carburettors are now set up better but I will have to get a new linkage pivot arm made.
    They are running beautifully and sunked them (pleural of synced) only problem I cant get them to idle below 900 rpm

    Never tuned a carb before.......taking them out on the road tonight .....they make a strange noise but gosh responsive .......got to be careful flooring it the front of the bus pops up and we are away.
    Parking in the garage smell of hot engine with no petrol!

    Rev I think I already have a buyer for the second pair though they may not want them if they find they will need to machine the pivot arm and the manifolds are awful to put on......bet it would be easier with the engine out though.

    disconnecting stock heater fan

    Hi there,

    I'm assuming you also have to somehow alter the intake where the old fan connects to the heat exchangers - or... is it just left open for the intake so the inline bilge blower can suck new air through the excangers and up to my Melbourne feet.

    I'm doing this because a) i like the idea of getting rid of the engine bay heater fan and b) my engine bay heater fan is knackered.

    Cheers! Great thread by the way. Take home message = leave carbies be until I am rich!

    Dingo.

    Dear Dingo
    I have Left the opening in the engine bay for the heat exchangers so it sucks air from above the engine.

    I have now modified the linkage arm and shortened the spring return and the carbies are tuned (ended up having some assistance in the end)

    The empi manifold is a shocker to get on it literally took the longest time and my mates ground a socket to fit and needed a wobbly extension.

    How do they go.......did a couple of hundred km today and the only thing I did we shorten the return spring.

    The Finished Product

    The Carbies are now 180 degrees in the wrong direction to suit the cable on the right hand drive. Also Linkage arm modification shown.

    Note the changes in the linkage arm and shortemed spring

    These are the inline heaters...bought a couple of extras as they don't look industrial strength to me

    Fair play

    Doc,

    thanks indeed for the clarification. It's just ocurred to me that the heater sucks engine bay air off the showroom floor so my inline blower mod thing isn't going to change much. I'm doing it because my stock fan is stuffed (they're only $25 at the wreckers, though) but I like the idea of getting it out of the engine bay, for some reason. What I'd love to do with my inline is somehow rig it to the original levers so no more switches are required. There's already one for the driving lights, the radio (god knows why that needs its own switch) and a little red turbo boost button (the aftermarket window washers, my personal favourite). The dash is showing signs of the original 20-owner kombi. Clips here, ties there, knobs here, hippy paraphernalia there (in my case, a blue fluff lined glovebox). Rust every fu*&%ng where.

    I like your engine bay p*orn a great deal. I think what I might do is just take out my aircleaner and use a hairtie and an old tee-shirt over the intake ports. Then, with my inline fan and a can of fiddly bits chrome, I should be right up there with you!

    A very helpful post - much grateful.

    Dingo

    There is no accounting for taste.
    Love the hair tie and tee shirt idea......perhaps you could just open a can of refried beans eat the contents and open the other end ...splay the other end and voila a Velocity stack. as for your heater Hose problem......open a new thread and I'll try and get pictures of my system.
    I also use the original wiring to get over the multitude of switches

    How does all that wiring go Doc? Any problems?

    I only ask because our mechanic would want to tidy that all up ...... you should see his workshop and that might explain it!....:D

    So would I:lol:

    How come you are using carbon spark plug leads Doc??????

    Long carbon leads = resistance
    VW spark plug connectors = resistance
    VW rotor = resistance

    3x resistance = less spark

    and carbon leads = unreliable and limited life span

    Wiring is about to see a mark 3 conversion.
    The Leads aren't carbon but tightly wound spring wire 8.5mm

    Just want to say thanks for this as I bought Kadrons and like you the accelerator cable didnt "feel" right. Did the same mod to the cable link and rotated them 180* and it works great now. just have to fine tune the linkage and mixtures.

    Cheers
