Helpful Hints

with the engine warm.
2. Governor oil is the same oil as is used in the
crankcase
3. Cylinder leakage can identify the location and
the extent of an internal engine problem
Cylinder leakage of 25 percent or less is
acceptable
4. When checking engine compression the throttle
and the choke must be fully open to insure an
accurate reading
5. Normal engine compression at cranking speed
is 185 PSI.
6. The actual compression reading is not as
important as the relationship between all the
cylinder readings.
