miserable failure....(UPDATEd update)

[Brendan Walsh]

Huw nailed it(thanks Huw!), new oxs and cat installed last PM, mixture
is all happy now. Now back to my original question, where is the 0 for
tdc supposed to line up in the window for ignition timing? Just need a
reference point to start from(who knows where it was from the PO).
Also, is there an easy trick to get those "donut" seals at either end
of the cat to seal tight?(mmm donuts....) Even with new hardware and
new seals I've still got a small leak by the downpipe.

TIA 
Brendan
