Today, while doing the annual maintenance, I found this object right under the upper ignition cable of cyl. 4.
I noticed this part when I pulled the socket of the ignition cable from the spark plug.
To me it looks like a rubber sleeve which perfectly fits over the NGK spark plug but I have never came accross it and to my best understanding it also didn't fall off anywhere while pulling the socket.
My A&P said that he has never seen this part in a Rotax 912 installation.
I am more than surprised and also a bit anxious. The part does not show any kind of wear or environmental exposure. And it seems that it does not belong to the cable socket.
My hope is that someone here can enlight me what this object could be.
Thanks a lot
