Carbon Fouled
Soft, sooty, black deposits indicate incomplete
combustion caused by a restricted air cleaner, over rich
carburetion, weak ignition, or poor compression.
Overheated
Chalky, white deposits indicate very high combustion
temperatures. This condition is usually accompanied
by excessive gap erosion. Lean carburetor settings,
an intake air leak, or incorrect spark timing are normal
causes for high combustion temperatures.

BATTERY
A 12-volt battery with 400 cold cranking amps (cca) is
generally recommended for starting in all conditions. A
smaller capacity battery is often suffi cient if an
application is started only in warmer temperatures. Refer
to following table for minimum capacities based on
anticipated ambient temperatures. Actual cold cranking
requirement depends on engine size, application, and
starting temperatures. Cranking requirements increase
as temperatures decrease and battery capacity shrinks.
Refer to equipment's operating instructions for specifi c
battery requirements.

Battery Size Recommendations

Temperature
Above 32°F (0°C)
0°F to 32°F (-18°C to 0°C)
-5°F to 0°F (-21°C to -18°C)
-10°F (-23°C) or below
If battery charge is insuffi cient to turn over engine,
recharge battery.

Battery Maintenance

Regular maintenance is necessary to prolong battery
life.
