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.
