[Fot] Distributor Retard

[Steve Yott]

Wonderful retard!  This was an emission "feature" that would retard the
timing only at idle with the throttle plates closed in order to meet the US
emissions.  Unless you need to meet any state emissions test you don't need
this any longer.  What I normally do for customers is plug this system but
leave it connected for appearance reasons.  These cars are hard enough to
get them to idle correctly and adding in 4 more degrees of retard just
complicates the situation.  OH for the days of real gas!!

This is not a racing question.  I'm sure the ignition retard is often
disabled on 6 cylinder Triumphs.  Does anyone know why it was used in the
first place?  I have always thought it was strictly for emissions, which
became more restrictive in 1968.  Perhaps it improves combustion at low
throttle such as when decelerating or when descending a hill.  
Just curious.
