Europa-List: Cracked weld on exhaust downpipe

[willie harrison <willie.harrison@tinyonline.co.uk>]

Dear All

I found (actually Tony Kay found - thanks Tony) a serious crack in the
front left cylinder exhaust downpipe (Rotax 912S with standard Europa
exhaust system). The crack was where the pipe is welded to the sealing
ring which mates with the cylinder head. It had gone all the way round
and caused the ring and pipe to separate completely, although you
couldn't tell by looking as the pipe was still held in the right
position by its attachment to the muffler.

Has anyone else seen similar cracks?
