Some older types of system (e.g. Triumph
PI)
used separate throttle plates per cylinder
and a common idle mixture screw. With this type it is essential to obtain an accurate
balancethrough each throttle plate before any mixture setting is undertaken.
Thiscan be
done using Carbalancer or Colortune as described in Section
8.
Where separate mixture
control screws are provided for each cylinder, adjustment should remain synchronised,
by using the same turns for each screw during adjustments.
