With the engine warmed
up and idling, and the
chain brake engaged on
a saw, slowly roll the
engine over so one side
faces the ground
Now roll it back upright,
then roll the other side
towards the ground
Idle RPM should not
change more than 200-
300 RPM
If the idle changes the
engine may have an air
leak or other fault
