Steve,
I know perfectly well what a Colortune is.
When adjusting and balancing carbs you have to adjust several items,
mainly butterfly valves, and idle jets or in case of SU's and Strombergs
the needle jet. If you change one it will influence the other. Therefore
it is extremely handy if you have a Colortune (and calibrated vacu|m
meter for that matter, e.g. Morgans Carbtune) when setting up the carbs.
This will save you from changing the Colortune back and forth all the time.
I have been using Colortunes for about 40 years on Triumph Spitfire/TR6,
Mini, Morris Minor, Renault 4/16/21, Peugeot 305, VW Beetle/Passat, BMW
2002, Subaru, MGB, Austin Healey, Alfa, Jensen Healey etc. I even tested
them as a consumer researcher for an automobile consumer organisation,
the Dutch equivalent of the AAA.
If used properly you can set the CO value between 2 and 4%.
You buy them in the UK for about GBP 5-15 used and about GBP 20 new,
which is not a great deal of money compared with the rates of a repair shop.
Cheers,
