Diesel problems ?

[Flieger]

Hi flying the warrior with the Diesel engine over the summer I have experienced that the engine sometimes do not run as expected, it happens both in flight and just after takeoff, it is engine roughness ore misfire as it is like flying on 3 cylinders, from ground it is visible due to more smoke. It normally disappears after 15-20 seconds.
Do any of you pilots out there have any experience with that ?

Happy flyer from Europe....
