For any of you doing SU or Stromberg carb tuning, I would highly suggest using
Scott Fishers SU tuning guide available fron the team.net archives. Although
written up for SUs it's easily adaptable to Strombergs (what I did). It's
better than the procedure in the Haynes manual and it explains the use of
Uni-syn and colour tune along with troubleshooting hints. BTW, I use both of
these tools, (if you've got a good ear, the hose will sub for the Uni-syn) and
it was the best $50 I spent to get my carbs set up correctly.

c Chris, These are indicator tools that help in adjusting
carbs. Uni-syn measure the air flow to the carbs so both
are drawing the same amount of air. It is placed over the
opening of the carb and you adjust the idle screw to obtain
a mid range reading. Then placed over the other carb and
adjust to obtain the same reading. You are adjusting air
intake. Colourtune is for ajusting the fuel mixture. It is
a glass spark plug which is used inplace of one of the
plugs and as the jet is ajusted, rich or lean, the color
of the burning gases in the combustion chamber can be
seen. You adjust the color per the directions that come with
the device.
