Thanks for the quick response.  I don't have any pictures at present, and I 
think it would be hard to see the hose routes anyway.  I'll do my best to 
describe:

Hose from each rocker cover to twin fittings at 3 o'clock on the air filter
Hose from 7 o'clock on air filter to top of aux air regulator
Hose from aux air regulator to underneath of throttle body by butterfly
Hose from flat rear plate of throttle body to oil breather pipe vent
Dizzi vac and advance pipes from throttle body (I know these are ok)

Oil breather has only one cap, rather than two.
Aux air regulator is ok.  I can take of pipe to throttle body and engine 
will up revs to 2000rpm.  Block off pipe and idle remains unchanged.

Got to be that oil breather.........
