What these parts do

Spark plug — Replace annually or every 100 operating hours. Cross-reference equivalents from other brands usually fit.

Spark plug gap — Set with a feeler gauge before installing. A wrong gap causes hard starting and rough running.

Engine oil — Grade depends on operating temperature, not on the machine. Several grades listed below are all correct — pick by season.

Oil capacity — Refill amount after draining. Always verify on the dipstick; a slight overfill can foul the plug.
