You see, John knows what he is talking about since he has two color tunes
(hi boss).  A color tune is made in the UK by a company called Gunson.  It
replaces your spark plug during your testing, has a quartz glass window
that the centre electrode passes through.  When the mixture in the cylinder
burns you can see the color of the flame.  They are available at specialty
shops like Moss Motors in US or MiniMania, Se7en Enterprises, or other brit
bits places.  Last time I bought one I paid about $CDN40 (which is about a
buck and a half US these days :-)

I have used this beast to tune my Mini, VW Rabbit GTi (with O2 sensor
disabled), rototiller, and 2 cycle lawnmower (the color changes slightly
due to the oil).

Aaach, they're brilliant.  Go out and buy one, and a Volvo 850 as well.
