BioLion 799584 Carburetor Kit — a comprehensive replacement for select lawn mower engines

When engines age or wear, a reliable carburetor becomes essential for steady idle, crisp starts, and consistent power. The BioLion kit is designed to replace key components with precision-fit parts for popular 550EX, 625EX, 675EX, 725Exi and TB/M-series engines in the 140cc–163cc range. Rather than a single part, this all-in-one solution bundles the main carburetor with gaskets, fuel filters, an air filter, and a spark plug to simplify shopping and installation.

What’s included in the all-in-one kit

  • 1 × carburetor
  • 2 × gaskets
  • 2 × fuel filters
  • 1 × air filter
  • 1 × spark plug

Compatibility and fit

The kit is designed to replace reference numbers including 799584 and related variants, and it fits engines in the 550EX, 625EX, 675EX, 725Exi family, plus TB110, TB200, M110, and M220 series. Always verify your engine model and part number before purchasing to ensure a proper match.

What you might experience with a full replacement

  • Quieter operation and steadier idle due to clean fuel delivery and a precise air-fuel mix
  • Rugged construction and durable components designed to withstand engine vibration and outdoor conditions
  • Simplified maintenance with a single kit covering essential wear parts
  • Potential for improved starting consistency and reliable performance in variable conditions

Warm notice: Please double-check your original engine model and part number to confirm compatibility. If you’re unsure, our team is available to help verify fitment before you order.

Installation and care tips

  • Follow your engine’s service manual and use appropriate tools when replacing the carburetor and filters
  • Inspect surrounding fuel lines for cracks or leaks and replace as needed
  • After installation, run the engine at a range of speeds to confirm the correct air-fuel balance

BioLion designs components to withstand routine use across mower seasons, with an emphasis on dependable parts and predictable performance under common outdoor conditions.
