💡 Why do small outdoor power engines lose compression over time?

Worn rings allow compression air to escape past the piston surface reducing power output significantly.

- Dust particles enter moving parts creating friction and heat buildup within the crankshaft area

- Cleaning and replacing internal components restores maximum energy efficiency and longevity.

- Regular maintenance prevents costly failures by keeping seals clean and lubricated properly.
