one of my friend got same trouble with a DynamiC WT9 but with a 912 ULS.It seems it was a vibration of the Aeroduct flexible ducting to the air box because it was too loose.A better tie solve his problem.

Had a similar loss of power which was found to be caused by the plugs of one cylinder fouling with carbon during a 5 hour flight. The problem was the Cee clip holding the port (left) needle had come off and the needle retreated to the top causing a very rich mixture, coating the plugs with so much carbon it shorted the plugs. The other cylinder (further from the carby) on this side also had a carbon build-up on the plugs but not as bad. Cleaning the plug after re-seating the needle and the engine ran normally.

Hello everybody

We finally bought a new engine for another aircraft and got a 55% discount from Rotax on this engine to compensate for the engine with the wornout crankshaft.

Thanks to those who tried to help me with this problem
