    I don't think any of the carbies fitted to CX's have the jets on the outside of the carby .............

    all the jets are on the top of the carby. You pull them one at a time so they don't get mixed up. You need to unbolt the plastic inlet first.

    You didn't change that fuel filter right ?

    Supposedly there is a spring at the back of the carby that will allow access to a jet that controls the revs.

    Cleaned out the top jets last week

    This isn't a blockage, more of ongoing problem where the revs drop out. Happens once every two months, then rectifies itself overnight.

    The car goes fine with the choke pulled out, but without the car stalls.

    I think you are talking about the mixture screw.

    These were down a hole at the back of the carby that was originally blanked off to make it tamper proof. I would be sure that the plug has dissappeared now. You need a small slotted screwdriver that will go down the hole and engage on the top of the needle insert. You then screw it in (cw) to make the idle mixture leaner and out to make it richer or to take the needle insert right out so you can squirt some cleaner down there.

    So the way I used to set up the idle was to sequentially adjust both screws until a good comprimise was reached. Use the butterfly stop screw to set idle speed and then screw in the mixture screw until the engine starts to conk out, then take out just a tad to make the idle reliable.


    Cheers,
