BRILLIANT! Instead of using an Air Fuel mixture guage to AT LEAST get in
the ballpark for good power and MPG's, you want him to put it "in the
middle and hope".

I thought so, thanks.

Seeing as he still has the metal plugs blocking the mix screws and no
working stepper motor 'and' the factory setup had the pins in the center
of their travel when the mix screws were originally set, would you have
a better suggestion?

And I have yet to see any back yard mechanic have an 'air fuel mix
gauge'. The CJ's are Carburated Jeeps that were manually tuned since
they came out in 1949. Only since the sad demise of mechanics and the
rise of 'technicians' that only know what a computer tells them is wrong
do you have tools like that.

It's not a computer Mike, everything that lights up and is attached to
sensors isn't necessarilly a computer... It's a scientific measuring
device for combustion temps that can tell you if you're running too lean
or wasting gas (and POWER) by running too rich. It's a HELL of a lot
more accurate than your gut feeling, and it's WAY WAY freakin more
accurate than your "hope" technique.

If "computers" and scientific data providing guages caused the demise of
mechanical yokles and non-adapting-stuck-in-the-past technophobes then
the world is a better place...
