Exhaust Analyzer Needed-Help please!

How reliable do you want it to be?
Here is a cheapie one on ebay # 270359895137 or 250391421987

Or do you need more than CO testing?  Maybe a professional one?
Here is a better one with more abilities ebay # 190293031565

The first one I bought was similar to ebay #180337196690 and probably is
buried in my basement or garage.  I only paid $50 new for it maybe about 35
years ago from JCWhitney.  I guess it worked but I was probably too new
about auto mechanics.  I think I got my Beetle to pass emissions test
though.

I want to get one to set the 34PICT3 carb on my 1973 Beetle to the
correct
air/fuel ratio of 14.7:1 for stoic.

You need it slightly richer than stoich, for optimal performance and
driveability in these engines. It would run cooler too.

I think I might try one of these Colortune Engine Analyzers with a
mirror.

Procedures for setup and use are simple. After warming up the engine,
remove the spark plug in the cylinder that is to be checked and
replace it with the Colortune plug.

Note: I am paranoid abut this since, I only remove my plugs when the
engine is cold from sitting overnight to avoid stripping threads.

Here is part of the ad:
Therefore, the best way to know the mixture is to be able to "see" the
mixture! This may sound a little strange, but the color of the flame
produced around the spark plug during combustion changes as the
mixture changes.

Typically, if you could see the flame color it would be a hot blue
when the mixture is just right, a yellow when it is too rich (more
fuel than required for any given amount of air) and a white/blue when
the mixture is too lean (less fuel than required). Interestingly these
changes in flame color occur very quickly as the engine operating
condition is altered, such as when the throttle is opened, when load
is applied or during deceleration.

Procedures for setup and use are simple. After warming up the engine,
remove the spark plug in the cylinder that is to be checked and
replace it with the Colortune plug.

Now attach the included high tension lead between the plug and the
boot end of the spark plug wire (it will work with either terminal nut
ends or plain threaded terminal configurations). Run the engine and
observe the color through the insulator area of the special plug while
performing your adjustments. For difficult-to-access spark plugs, the
kit includes a 2-piece viewerscope with an attached mirror. The
viewerscope is placed over the Colortune plug and lead, such that the
combustion color can be observed at practically any angle!

I would not waste my money on the Colortune, there are several gas analyzers on
the market semi cheap, I have lost the links but if you do a couple of searches
over at the Shoptalkforums you will find them.

If you are to do it on the cheap get a heated Lamda sensor and use a regular
volt meter to get stoic.

I would not worry about any of this with a stock carb setup, check the jets so
they are recomended for your engine and use the idle mixture screw to achive the
higest revs when idling(The manuals always tell you to back off 1/4 of a turn
from there, but I always leave it att higest revs).

I have all the carb data for most T1 and T2 engines in a manual if you give me
engine and dizzy code.

Thanks. That is what I usually do.  I used to set it that way plus an
extra 1/4 turn to allow for a margin of error.

Instead of getting the exhaust analyzer i think i might get some of
those neon tube lights that fit underneath.

Aircooled.net both rents and sells the Innovate kit.

The first of the two Aircooled.net links also explains the correct
air/fuel ratio for a VW.
