What comes in the Hipa MS 290 carburetor kit and why that matters?

The kit includes the carburetor plus several installation parts so you won’t need to source small components separately. These extras reduce downtime and the risk of misplacing essential pieces during repair. Everything ships together so you can complete the replacement in one service session.

How durable and reliable is the Hipa replacement carburetor?

Hipa specifies corrosion-resistant materials and a tested assembly process to improve endurance in outdoor, engine-heat environments. Brass components and an anodized aluminum body resist wear, while composite rubber diaphragms maintain fuel control under varying temperatures. Each unit undergoes a wet-flow test that mimics running conditions to verify consistent fuel delivery before shipping.

• Anodized aluminum body for reduced corrosion
• Brass fittings for wear resistance
• Rubber diaphragms engineered for flexibility and sealing
• Wet flow testing to simulate engine operation

Do I need to adjust the carburetor after installation?

This carburetor arrives factory tuned and typically requires little to no initial adjustment for most saws. However, because local altitude, fuel blend and engine wear vary, a brief final idle and high-speed check is good practice. Always double-check your engine model number and test under safe, no-load conditions after fitting.

• Factory-pre-tuned to reduce setup time
• Quick idle and high-speed verification recommended
• Adjustments only if performance differs due to altitude or fuel

Who is this for: The Hipa MS 290 Carburetor kit is meant for owners and technicians servicing STHIL MS290, MS310 and MS390 chainsaws who want a comprehensive, ready-to-install replacement. It suits landscapers, arborists, rural property owners and DIY mechanics who prefer to replace the carburetor and related consumables in one repair job rather than sourcing parts individually.
