Greetings from Kenya.  I've saved up a few questions for the network, 
perhaps someone out there can help.

1.  New regulations here dictate that we must now all fly with 406 ELT, 
and especially recommended is the Artex 406 (PLBs will not do here).  
This requires that for composite aircraft, the skin of the aircraft must 
have radial metallic strips, 1 inch wide, in the shape of a 6-point 
star, extending out for 24 inches in all directions.  Seems a bit 
excessive for a Europa, where can we find that space?  Behind bagage bay 
is obvious best bet.  Will alumnium strips work (I have sticky aluminium 
tape, 2" wide).  Has anyone fitted this arrangement?  Does anyome have a 
mod approval, STC or something for the Artex 406 installation in a 
Europa, that I can wave at aviation officialdom here?

2.  My tailwheel goes through bearings at the rate of knots, must be our 
dusty runways.  But it is costly to fit new tailwheels, when the tyre 
itself is fine.  Has anyone tried to fit the bearings available from 
Aircraft Spruce into the Europa tailwheel?

3.  Two weeks ago I got into the Europa (Classic, 912UL), started up, 
and had very rough running.  Under the hood, found that the left carb 
was leaking back through the connection to the plenum chamber, theres a 
small hole for water clearance, and fuel was pouring onto the ground.  
Further investigation revealed that all this seems to be because of an 
overflowing float chamber.  The float 'needle' (with viton tip) looks 
absolutely clean, no grooves on its face, but no adjustment of the float 
bracket will stop the flow.  The floats are fine.  Has anyone had this 
problem after just 500 hours of flying?  The fuel goes through an Andair 
gascolator upstream, so I am not sure what contamination caused this.

Thanks, and all best to all for the New Year!
