Hello everybody!

Any idea/suggestions about where/how to find a replacement for this ignition coil?

(It's from a Kubota GH250-Q-1-SO-UK2 engine)

All tips and ideas welcome!
Thanks

Darn... I got a new coil by mail. Replaced it. But no spark :-(
Any idea what it could be? I was sure it would be this ignition coil but there is something else.
Everything seems to be okay but no spark.
