    Hi all,

    The carbs in our '73 2 lt need rebuilding - throttle shafts need bushing. Can anyone recommend a good carby shop that does this work in Brisbane, or are there some good replacement carbs available?

    Cheers
    Matt P

    Leon's motors.
    Also do set up on dyno if required.

    73, 2l ? Assume engine swap.
    Double check it is 2 litre and that carbs match motor.

    Rebuild of originals likely cheapest / best option with least hassles.

    Hi Leon,
    It was the motor in it when my wife bought it about 20 years ago, she was told the motor had been reconditioned. I was told it was a 2lt by the engine number starting with 'CA'. It has been running for years with the twin Solex carbs but with the butterfly shafts worn and sucking air it's running like a hairy goat. Any suggestions who to take them to?

    Off Topic: I think I sold you some bits and pieces when I had Metric Cruiser Customs, back about 12 years ago. Was your workshop over Salisbury way?

    CJ is a 2 ltr.
    According to Muir's, a Dec. 73 CA would be a 1700 with alternator instead of generator....complete engine number would help narrow it down.

    Thanks guys,
    Well the engine does have an alternator, and was told it was a 2lt by one of those VW Specialists!! So it's likely to be as said a Dec '73 1700. The car is at my work shed at present I'll get the full number tomorrow.

    Cheers
    Matt

    Have re-kitted many of my own over the years as well, but this needs the shafts bushing and I have got the machinery to do that.
    The Engine Number is : CA 045824

    Leons motor recently rebuilt my carbs. It is a 2 litre engine that was jetted for an 1800. After re-bushing/re-jetting achieve 25% increase in power. Leon has the dyno setup. I am very happy with the work done at Leons. Leons actually send the re-bushing job off to another specialist.

    I would advise checking that the engine number on fan shroud matches the one on the block, just in front (behind?) the oil tower to be sure as shrouds appear to be interchangeable.

    As Paul said.
    Double check number on case matches fan shroud.

    I rebuild carbs, I'm in Adelaide. I do everything, including all that the others don't.

    You need to be sure of the motor, CA is a 1700 engine number. Also check the engine number on the case, just below the breather tower between the fan housing. I'd recommend popping off the rocker covers and quoting the cylinder head part numbers which may give more indication of whether or not it might still be a 1700. CJ, GD, GE is a 2L engine number.

    I'm currently working on a pair of 1700 Automatic carbs and had to convert the RH carb to 1700 Auto spec to match the left carb as the customer's RH carb was incorrect. This involved drilling the throttle body, housing and changing some of the pressed-in fixed jets.

    They are going together now, below re-bushed throttle bodies, and repaired accelerator pump covers (repaired, welded arms-redrilled pin holes, new pins, lapped sealing face)... Just like new. Rest of the carbs will be built with the same attention.

    1700 Auto carb rebuild now finished... even 'that little rectangular box', the central idle circuit choke gets rebuilt... No stone left unturned, Pierburg specs on hand for what they are...... The RH carb wasn't a 1700 Auto carb, but completely mis-matched 1800 manual carb.. The RH carb, due a lack of suitable cores was modified from a 1700 manual carb, re-jetted(both fixed and removable), 'Auto' ports drilled and Throttle body modified to become 'Auto 1700' spec. ;) They are now good to go in every sense.
