10. IGNITION/BOOST CONTROL UNIT OPERATION
A. The Ignition/Boost Control unit is
designed to retard ignition in rela-
tion to boost.
B. The unit is adjustable from 0° of
ignition retard to 4°of ignition re-
tard for each pound of boost, up to
a maximum of 20°
C. Using the middle position (knob
pointing straight up) as a starting
place, adjust the ignition retard
knob until just beyond the point of
detonation. Use third gear for test-
ing in a safe area or road. Adjust
the retard according to changes in
altitude and fuel quality.
