in this case I would assume that your "idling throttle" might be too high. I have the experience that with Daimler fluid flywheel cars that the idling speed is rather low compared to other cars e.g. 500 rpm only. If you have too high idling revs, the flywheel takes too much momentum and you can hardly stop the car or keep the car stopped. Even worse when your brakes are weak.

Of course you might need higher idling revs and to open the hand throttle to start the car. But as soon as it is running smoothly you should close the throttle (and the choke). Otherwise the car jumps forward or backward (in return gear) and cannot be stopped as outlined above because the flywheel transmits too much momentum.

Hope this helps

Hi Beat,
Yes, this could also be the cause of the problem. The idling speed is, if I remember, 700-800 rpm. The car tries to go a little without adding throttle. I'll have to check and adjust this.
My problem is bad English. I did not understand the principle of this gearbox at the beginning of its use completely.
Thank you very much for your help and advice.

Have a look at You Tube. Put fluid flywheel in the search. Various videos come up but I don't know what language they will be in where you are. Do not confuse fluid flywheel with torque converter they are 2 different things.

I've just looked at "Fluid Coupling - Principles of Operation 1953". There is a good demonstration about 2 minutes in.

Hi Nick,
thanks for the advice. Perhaps the best video I've found is this . So the theory is clear to me. Now comes the practice. :D
I buy a brake parachute, for sure. :D

Here is the original workshop manual. The English is 'old' so it may be a little hard to read

Today I tried it again. The idling speed is 500 rpm. The car stands against a slight slope. I select the second speed, press and release the change gear pedal, I release the brake and the car does not back off. On a straight road, it tends to move slowly. Does the oil density affect it? I do not know exactly what kind of oil I have in a liquid flywheel, but I think 15W40.

I always used a straight 30 oil in mine.

I will find out what oil I have and if necessary, replace it. Thanks.
