Keep in mind that your carb has a split personality:

"Idle" circuit
"Butterfly valves open" circuit

there's more to it that that, of course, but most of
what you notice at idle is idle mixture settings
AND/OR vacuum leaks.



There is a guy locally that has a Sun
diagnosticmachine and charges a buck and a half to
feel your car up with it.  It can even tell which
cylinder is firing poorly on the scope!  -Carnal
knowledge of one's engine never felt so good!

I had my carb rebuilt for $250.00 (the carb rebuilder
referred me to him, and he does 4 cars per saturday
session).

I watched in wonder as he put the gas analyzer up the
car's kazoo and proceeded to adjust the idle mixture
setting.  He also detected a miss on cylinder no 7,
and that turned out to be the vacuum hose that led to
the parking brake release mechanism. - That was that
hiss under the dash that I'd been merrily listening to
and ignoring for the last 6 months!  The vacuum line
plugs into the manifold on the no. 7 runner, causing
lean when hole is present in vacuum lines on it!! 
Duh.

Obvious?  Maybe, but that $150 shortcutted a lot of
brain activity, and that's worth something.  David
(who just wrote in) was there for that, too, and it
was highly entertaining, from a car-guy point of view.


Rebuilt carb, new fuel filter (!!!!), and a practiced
hand to tune it, and the car is like silk at idle!! 
WOWEE!  

If you're in the SF Bay Area, call John F. Bishop at
650-343-4860 for a good time (carb-wise).  He is in
Burlingame near the IT'S-IT factory on 101.

He had some apprentice that was bragging about tuning
and how he'd been in this magazine and that and how
they were testing some gadget and all that.  I wasn't
as impressed as that guy had hoped, but it made for
encouraging background noise as I was entrusting my
prize to john, because I'm stingy and hate paying
labor fees if at all possible, but it was money well
spent!
