Here's why:
* Two-stroke engines are known for their simplicity and power-to-weight ratio. They mix fuel and oil directly and have fewer moving parts.
* Four-stroke engines are more common in everyday applications. They have a separate oil system and are generally more fuel-efficient and quieter than two-stroke engines.
Briggs & Stratton's "6.0" refers to the engine's cubic inch displacement, a common measurement for four-stroke engines.
