Make sure the auxiliary air regulator is getting power and that all the
plumbing is connected correctly. When cold, if you clamp off a hose to
the valve, the idle speed should drop. When warm, clamping a hose should
make no difference.

Subject: SETTING IDLE

Howdy,

Out of the blue the idle on my 82 air cooled Westy (Federal model) is
acting
up.  I set the idle to 800-950 rpm when warm per the Bentley.
Everything is
great when the engine is warmed up.  However, when the engine is cold it
sort of bucks and coughs along at about 600 rpm.  If I bump up the idle
to
800-950 when cold the engine idles great, but after it has warmed up it
idles at 1500.  Sow what's the scoop.  Within the last year I replaced
both
the temp II sensor and the auxillary air valve.  I suppose the tempII
sensor
may be acting up again, but it seems unlikely.

Thanks,
Jake
