Dynamic Test
To check ignition timing, use Bombardier timing
light (P/N 529 031 900).
717 Engine
NOTE: To perform this procedure, make sure to
use a stroboscopic timing light rated up to 6000
RPM. Otherwise, an inaccurate reading will be ob-
tained.
The ignition components are affected by temper-
ature variation, therefore, timing must be checked
when engine is cold, after idling for a MAXIMUM
of 20 seconds.
1. Connect an induction-type tachometer (P/N 529
014 500) to spark plug wire.
1. Tachometer pick-up
2. Connect timing light pick-up to MAG side spark
plug wire.
1. Timing light pick-up
3. Start engine and point timing light straight in line
with timing tool slot. Bring engine to 6000 RPM.
1. Timing light straight in line with tool slot
CAUTION: If engine is to be run more than a
few seconds, engine must be cooled using the
flush kit.
4. Check if PTO flywheel mark aligns with timing
tool slot.
NOTE: On this system, timing advance decreases
as engine speed increases.
If timing mark aligns with tool slot, timing is prop-
erly set. If mark does not align with tool slot, re-
check PTO flywheel mark before adjusting ignition
timing to ensure PTO flywheel has not loosen.
