Understanding Small Engine Repairs
Small engines can be found in a variety of equipment, including lawnmowers, generators, chainsaws, and more. These engines are typically simpler than their larger counterparts, but they still require specific knowledge and skills for effective repair and maintenance.
Common Types of Small Engines
1. Two-Stroke Engines: Common in smaller equipment like chainsaws and trimmers, these engines are lightweight and powerful. They require a mixture of fuel and oil.
2. Four-Stroke Engines: Found in lawnmowers and generators, these engines use separate oil and fuel systems, making them more efficient and cleaner-burning.
3. Electric Engines: While not traditional small engines, electric motors are often included in small engine discussions due to their prevalence in consumer equipment.
