I have no problems with reading comprehension, unlike how you seem.

I will quote the TSB that was posted:

NOTE: THE IDLE MIXTURE SHOULD ONLY BE PERFORMED IF THE ADJUSTMENT
SCREWS WERE REMOVED DURING CARBURETOR OVERHAUL FOR CLEANING
PURPOSES

Or as it politely doesn't say: If you screwed up and forgot to count
the turns upon disassembly like the other manuals state.

Pay attention now, I'll type it slow even....

It does not say to do this as part of a 'normal' tune up.

It does not say to cut up or leave cut up your carb up so you can do
'field' adjustments.

In fact it pointedly states, Quote:

"10. Install RTV in the idle mixture screw plug holes."

That would effectively turn the carb back into it's 'stock' form with
only the idle speeds and choke rich available as 'field' or 'driveway'
or 'tune up' adjustments.

If it goes out of emissions spec, it needs to be cleaned, not cut up and
dicked with to try and compensate for a blocked tube or passage.

Simple eh?

There, now I hope that wasn't too difficult to understand was it?

Man, you 'really' need to actually 'read' what I write, not just guess
at it's meaning....

The above was taken out of context and you know it.

For Sure there is a factory stock adjustment on a freaking carb, manual
or computer controlled! I stated that wayyyy back in this thread.

'Stock' means plugged idle mix tubes as that TSB also indicates.

Hmmm, I have the below message in my sent box and someone quoted it on
the newsgroup, but I can't see it or find it there on my server so I am
going to repost it.

It was sent Sunday, Aug 10th at 12:13 PM.

---------------------------------------------------------

See, here you go again with all this 'adjustment' BS.

There is 'NO' idle mix adjustment on a stock Carter BBD with a stepper
motor!

You seem to have a mental block on this simple fact and keep insisting
you have to cut up or drill out a carb to get it running right, rather
than cleaning and putting a kit in it to properly fix the problem.

'My' carb has nothing to do with the scenario I outlined, mine is 'not'
stock and I do not have a computer moving the stepper motor.

I will fill in some below just because I am bored...

No functioning computer on mine.

It is a 'factory' set that is 'supposed' to be set exactly back as it
was before it was disassembled for cleaning.

The carb kit also comes with replacement 1/4" x 1/4" plugs that are to
be pressed back in after a clean.

>
> Why is it important for the factory settings to match this, but not adjustments made in the field?

There are no 'field' adjustments available on a 'stock' BBD with stepper
motor besides the idle speed and choke richness.

>
> If they should never be moved, why are they adjustable anyway?

For a base or factory setting to have the stepper pins dancing evenly
between step 2 and step 3. In other words to have it 'exactly' in the
middle of that 2-3 step pulse so the rich/lean pulses are timed even
giving a stable emissions mix. (see my original scenario)

Carter just uses the exact same base plate for the regular manual BBD
and the electric BBD. They just block the electric BBD's mix screws
with solid plugs, unlike the tin cap they use on the manual BBD's screws
that can be popped out with a screwdriver for 'field' adjustments.

>
> Why does the factory service manual give you the procedure to remove the plugs, and adjust the mixture, but mentions nothing about D/A timing pulses?

There are two different Carter BBD's, the book has adjustments for the
manual carb mix but for the electric one, it just says, Quote: 'Idle
adjusting needles (part # 54)- turn in until lightly seated, then back
out the number of turns counted on disassembly'. End Quote.

Pretty simple eh?

If the carb has a fresh kit in it and everything is clean, the factory
setting is the only correct one.

To get a messed up one back to factory would require a sniffer in the
tail pipe while you are adjusting it.

>

Yup, it does.

And if the factory set on the mix screws is still there, then the 'book'
adjustment on the vacuum piston assembly is correct.

Start messing with the mix screws, and then you need to start messing
with the vacuum piston adjustment to get the right high speed mix to
pass emissions. Been there, done that, on a 'manually' set up carb
only.

>
> Why is that stuff adjustable?

No two carbs or engines are made or adjusted 'exactly' the same. The
factory has to be able to fine tune everything.

And some parts like the base plate are just used on different models to
save design costs. They just modify them slightly like with the solid
plugs on the mix screws instead of the pop off/out caps.

Like they put the sol-vac unit on all the carbs, but only the automatic
or AC equipped vehicles have the set screw in it so it actually
functions.

The 'only' reason to ever take out the plugs on the mix screws on the
base plate for the electric BBD is to disassemble them for proper
cleaning.

I hope so. Maybe I explained it well enough for you to catch on...
