Questions to ASH26E or ASH25 MI owners

Hi,
A few questions, on behalf of a friend, to the ASH26E owners.

On the Wankel Mid-West AE50R engine:
- Has anyone ever had any leaks problems in the cooling system ? There's
quite a fair amount of cooling liquid being lost at every run. Further
inspections did not show any leaks in the pipes, which would indicate a
problem on the pump itself. Gaskets somewhere ?
The engine is now also leaking fluid when cold.

- On the same matter: does anyone have a drawing of the engine ? It would
help identify the source of the leakage.

- Has anyone ever used the NGK spark plugs ? to what result ?

Concerning the ASH26E itself:
- Does anyone have the 3000 hours inspection program available in eletronic
format ? or a copy on paper...

Is there an ASH26E specific forum somewhere ? could not locate any using
google...
