-
Spark Plug Types and Heat Ranges
Various spark plug types exist, categorized by their heat range. The heat range refers to the plug’s ability to dissipate heat. A “cold” spark plug dissipates heat quickly, suitable for high-performance engines operating at higher temperatures. A “hot” spark plug retains heat longer, better suited for lower-speed, lower-temperature applications. Selecting the correct heat range for a specific mower engine is crucial for preventing pre-ignition, fouling, and maximizing performance. Using an incorrect heat range can lead to engine damage and reduced efficiency.
-
Spark Plug Gap and Adjustment
The spark plug gap, the distance between the center and ground electrodes, directly impacts the spark’s intensity and effectiveness. A gap that is too narrow can produce a weak spark, hindering combustion. Conversely, a gap that is too wide may prevent the spark from jumping altogether. Proper gap adjustment, specific to each engine model, ensures optimal spark performance and efficient fuel combustion. Gap adjustment tools facilitate accurate setting and prevent damage to the electrodes.
-
Spark Plug Condition and Replacement
Spark plug condition provides valuable insights into engine health. A sooty black deposit indicates a rich fuel mixture or a clogged air filter. A white or light gray deposit suggests a lean fuel mixture or overheating. A normal spark plug exhibits a light tan or brown color. Regular inspection and replacement, typically every 25-50 operating hours or as recommended by the manufacturer, ensures consistent spark performance and optimal engine function. Ignoring worn or fouled spark plugs can lead to starting difficulties, reduced power, and increased fuel consumption.
