912 ULS idle throttle problem

Do you have any vibrations at Idle RPM or lets say below 2500 RPM?

Have you noticed any fuel from carburetor's overflow pipe after engine shut down?

Probably dirty carburetors or heavy floats or out of balanced propeller may be the reasons. Are you sure that carburetors are perfectly synchronised.

No vibrations, floats checked and between the limits.  I will check the overflow, I have the feeling, that there was some overflow. Propeller was checked last year.

Did you manage to solve the issue?

Hi, we are not 100% sure, but it seems, that there was 3 problems:

- no min throttle stopper on the plane, therefore it was possible to see some movement at the carburettors idle-stop bracket;

- the cables were not adjusted equally, it means on one carburettor there was more movement, than on the other;

-  carburettors got a full set of new seals.
