After a lot of experimenting I traced the problem to the relief valve. Rotax wanted to sell me a new pump. The fix was to make shims out of ,016 and .025 aluminium to place under the check valve spring to find the right combination to solve the problem. Cheap and it worked..

I thank you very much for your assistance.

I found a rotax service bulletin with drawings and instructions for the shim and its location, etc. All pretty straight forward. Now to find the time to open the cowling and have at it. Thanks again.
