    Default Oh no, Solex CISAC carburettor

    Hi froggies

    For those who are familiar with the Soles CISAC/Z1 carburettors, Im sure the heading isnt too unfamiliar. If there is a carburettor I would rather not have around its one of those- and now Ive just bought a new one.

    The story is that my 505 has one of them and until I changed it yesterday it had been sitting there for twenty years. The reason for changing it was a combination of deteriorating economy and the fact that the auto-choke had been completely ruined by the previous owner.

    Thus the only way to apply the chose was to open the hood and engage it manually, which was becomming a real drag. Im not personally fond of auto-chokes but as it was the only one I could get, I thought Id go for it, at least it should give a few years of sterling service NOT.

    The issue with this new wonder carby is that it has caused even worse hard starting then the previous one which would be fine the rest of the day, once you had manually engaged the choke in the morning and started it up. In other words, once it has been running it would be a half-kick starter the rest of the day.

    Now this new wonder just doesnt start in the morning, nor when its hot. In the morning you just to keep cranking for ever. Once the engine has been running, it will start well within the first two minutes stopping the engine but once it has been standing for say 10 minutes its hard to start and it starts in a way that would suggest that the choke is one, ie. it stumble starts with lots of smoke.

    After a few seconds it starts running smoothly and continues like that with no problems except a slight tendancy stumble very slightly when you apply accellerator abrubtly. Now, under transportation the solonoid switch (it has only one at the front)on it has been damaged and I am therefore wondering whether this could be the cause of the problem both in terms of cold and hot starting.

    The reason for this speculation is that the solonoid switch on the old one was also disfunctional and has never been working as long as I have had the car. Thus I dont have any experience with running the car with the device working and quite franckly Im not too sure what its function is.

    I am therefore a bit in a dilemema of not knowing whether this new carby has a choke problem or whether its that solonoid that is the problem. I have taken off the solonoid and will take it to the dealers for replacement today. However, since I have never had the old one working Im not even sure whether the wire connection for it is actually working and in what sort of way it should receive current, ie whether it is only at startup or whether it should receive current at all time while the engine is running.

    Any ideas before I fling both carburettors into the ocean??

    Hi Lennix,
    I assume this carburettor is of your 1986 505GL Estate.
    If it is then it sounds identical to the one on my 1986 505GR Estate.
    The only difference might be because your car is of East African origin and my car is of English origin. (I imported it into Australia in 1993)

    I am sorry to hear of your problems because I have to say that my carburettor has performed very well over its 400,000miles so far.
    The main thing I have had to do is to give it a good dismantle and clean about every 2-3 years as the idle circuit seems to get blocked by very small particles after a while.
    The other main problem was the small water jacket which bolts on to the automatic choke. This eventually collapsed due to corrosion.
    As my car is imported I couldn't get the gasket set and parts in Australia so I searched the internet and got them from a carburettor specialist company in England. This only took about 10 days.
    The solenoid device on the front of the carburettor seals the float chamber from the atmosphere when the engine is stopped. This prevents fuel from evaporating to the atmosphere when the engine is off.
    On my car there is also a second wire in the same circuit which connects to a small heater disk located very close to the idle mixture adjustment screw. In cold conditions this helps warm the fuel and prevents icing as well as better fuel vapourisation. I disconect this in our hot summer conditions in Perth.
    Check first that there is water moving through the tube to the automatic choke. This 'small' pipe can get blocked and if it does then the auto choke will never switch off.
    OK - your problems.
    I suspect that the autochoke has not been adjusted. The last time I did an overhaul on mine I removed all the adjusting screws and when I put it all back the car was difficult to start from cold and the auto choke wasn't operating properly. It took me a few days to get the adjustment correct again.
    Refer to the Haynes manual No 762. Pages 94 and 96. In particular on Page 94, Section 12 items 13, 14 and 15. This tells you how to adjust the fast idle (auto choke). Along with adjusting the normal idle when warm you should get the desired result. For my car I took a few days to get it right, each day making adjustments before the engine was warm.
    Also check the height of the float in the float chamber - again refer to the Haynes manual for this.

    My last comment is that Arusha is some distance inland and it would be a pretty good throw from there to get to the ocean!

    Good luck with the carby.
