Rob,
The IPC calls up the new flywheel hub on the 80Hp & 100Hp engines, and the intention from Rotax was to introduce it on the 80Hp engine some years ago.
Both the 80Hp & 100Hp engines should have the soft start modules & flywheel. If you could help with the serial numbers where they were introduced on the 80 &100Hp engines it would be appreciated.
Your help here is great...Much better than we can get locally.
