Unlock Your STIHL MS Series with the NIMTEK MS290 Repower Kit

When your chainsaw loses that dependable bite, you want a solution that fits right and revives what you rely on for property maintenance, wood cutting, or seasonal cleanups. The NIMTEK MS290 Repower Kit is designed as a direct OEM replacement for select STIHL models and delivers a complete refresh in a single, ready-to-install package.

Designed for STIHL MS290, MS310, MS390, 029, and 039 chainsaws, this kit bundles essential components that address the engine’s core systems—fuel delivery, ignition, and air filtration—so you can get back to work with minimal downtime. Each part mirrors the engine’s needs, offering a cohesive upgrade without guesswork or mismatched fittings.

What’s in the kit

• Carburetor aligned with part numbers for a direct OEM replacement
• Ignition coil engineered to deliver reliable ignition strength
• Air filter to trap dust and debris before it reaches the engine
• Fuel filter to protect fuel flow and stabilize performance
• Spark plug designed for consistent combustion
• Fuel line sized for steady fuel delivery
• Oil filter to support engine lubrication
• Impulse line and oil line for proper pressure and lubrication routing
• Includes all the lines and filters you need for a full refresh

Why choose a complete repower kit rather than buying parts individually? First, it offers a cohesive set of components that are meant to fit together, reducing the risk of mismatches. Second, the kit enables a faster turnaround—less hunting for compatible pieces and more time in use. Third, assembling a full refresh kit can be a cost-effective option compared with sourcing each item separately, especially when you factor in time on maintenance.

Real-world benefits and use cases

• Smoother starts and steadier idle improve confidence during routine cutting and limbing tasks
• Restored fuel flow and ignition strength help you power through tough wood when the saw is under load
• Clean air intake through the new filter helps maintain combustion efficiency and engine health
• Quick installation with a direct-fit design minimizes downtime and tool needs
