LOCTITE101 I just checked and my Sharma 09 is a drop in fit on the mount, so a little more punch for thee weight, it is fiited with a PAW stack,
The OS 10LA or TT10 davis heads would fit but the muffler would mess up that nice cowl martin
I think the orginal owner used an engine larger than 06 due to the engine mount
The Ladybird is still available around the internet as a full size or double size kit.
The ED Bee details are given here.

No doubt a modern slighty larger diesel would make it fly better as I believe they tend to be tail heavy.
