Detonation usually can be prevented, provided that
1) the engine is correctly set up and 2) diligent main-
tenance is applied to combat the detonation causes,
listed, preceding.

Damaged Piston Resulting From Detonation
Compression Check
1. Remove spark plugs.
2. Install compression gauge in spark plug hole.
3. Hold throttle plates at W.O.T.
4. Crank engine thru at least 4 compression strokes
to obtain highest possible reading.
5. Check and record compression of each cylinder.
Variation of more than 15 lbs. per sq. in. (103.5
kPa) between cylinders indicates that lower com-
pression cylinder is in some way defective, such
as worn or sticking piston rings and/or scored pis-
ton and cylinder.
6. Compression check is important because an en-
gine with low or uneven compression cannot be
tuned successfully to give peak performance. It
is essential, therefore, that improper compres-
sion be corrected before proceeding with an en-
gine tuneup.
7. Cylinder scoring: If powerhead shows any indica-
tion of overheating, such as discolored or
scorched paint, remove transfer port cover and
visually inspect cylinders for scoring or other
damage as outlined in Section 4 “Power Head.”
