Small Engines Project
Lawn mowers, go-karts and ATVs all run on small combustion engines. Learn about internal and external engine parts, tools, rules and regulations, safety issues, and career possibilities. Troubleshoot problems with a small engine, rebuild it and operate it safely.

4-H plays a pivotal role in youth development and public education at the Minnesota State Fair. More than 7,000 4-H youth have the opportunity to interact with the public and educate fairgoers through 4-H exhibits, demonstrations, performances, and 4-H promotion. More info.
Beginning to learn about small engines:
Identify engine parts and oil grade differences, demonstrate spark plug maintenance, understand the importance of safety labels and which machine to use for which job.
- Small Engines 1 - Crank It Up (40 pages) - Find this in the 4-H Mall.
Some experience with this project:
Classify small engine types, identify internal parts of an engine, adjust a carburetor, calculate compression ratios, seasoning their engines, describe effects of changing gears and follow procedures for tearing down an engine.
- Small Engines 2 - Warm It Up (40 pages) - Find this in the 4-H Mall.
Looking for a challenge:
Tear down and rebuild an engine's air and fuel systems, electrical system and engine base. Sharpen a lawnmower blade, match engine sounds to problems and adjustments, use diagnostic tools and explain calculations and considerations in determining whether or not to start a small business.
