RE: Spica Spider idles high

["Ian Lomax" <sfalfisto@domain.elided>]

Hey Bill,

Check the ignition timing first, as it will affect the idle speed.  The next
step is to screw in the idle air source, the tube that runs from the filter
housing to the aluminum block on the top of the engine.  Screwing it in
should lower the idle speed.  The throttle plates might also be misadjusted.
Check out the excellent instructions from Wes Ingram on how to check and
adjust them properly at www.alfaclub.org and make sure you make one change
at a time, so you can put it back if something goes wrong.

I'm not sure how familiar with the SPICA system you are, but if you're new
to it read all the instructions carefully before changing anything.

Good luck!

Subject: Spica Spider idles high


Hello Everybody:

I have a 71 Spider 1750 with original Spica injection. I bought the car in
Lake Tahoe (6000' elevation) and live and drive the car in the South Bay
section of LA (0' elevation).

At altitude, the car seemed to run fine, if sluggish. At sea level, the car
idles hat about 1500 rpm when warm (but runs like scalded dog).
Fundamentally,
it makes sense that the increased air density would cause the higher idle on
a
car that has no sensor and computer to compensate.

Question is this: Is there a simple adjustment to make to bring the idle
down?

Thanks,
Bill
