Noise dissapears above 2000rpm
Noise dissapears above 2000rpm
The symptom is that while running in low rpm (1200-1300rpm), pressing the throttle pedal to speed up, some strange noise comes, some knocking which sudennly dissapears at 2000rpm. It seems like something is a bit late while increase the rpm and it's gain on at 2000rpm. Nothing above it. It always dissapears in the same rpm.
Any ideas what that can be?
OM605 7,5mm Dieselmeken elements, mechanical pump. Timing is in place, adjusted to the stock value.

The quantity is low 85-90ccm. I'm really not on the borderline from the upper side.

Any suggestions regarding this noise?
This is the one that dissapears. If the engine is cold it is louder.

Check out it is working properlly. Sometimes they do not, cause of a design flaw. Using a older 605 N/A solve the problem.
But its definetly timing related... its god damm advanced...

Those engines in the videos sound really bad... my sugestion on the advance mechanism is still valid.
