Erich,
Boy, do I wish I'd read that two months ago. I appreciate the
gesture, but I'll be wriggling into the occupied monowheel tunnel to free
the throttle box and rebuilding with bowden wire............
Guess I should have had the sense to see that on my own!
Cheers, Ferg

| Patrick,
| Regarding the throttle cables. Remove and throw away the inner cable and
replace it with a solid Bowden cable/wire from ACS part number 05-15500. It
comes with a metal casing that you will not need so discard it. You will
need to form the end of the cable over an AN111 Cable Bushing and Redux in
place. This will be attached to the standard Europa throttle lever. The
open end attaches to the Rotax engine as per the manual.
| As an engineer I could never understand why Europa used a cable for the
throttle linkage. Cables are designed for tension not compression. It is
quite easy to kink a cable when using it in compression. The solid wire
Bowden cable is designed for compressive loads. Also using the Bowden
cables will over come and 'stiction' and there is virtually no play in the
throttle linkage. Good luck
