If your Stihl MS 170 is running too lean, it’s important to calibrate the carburetor to ensure optimal performance. Here’s how to do it:
- Remove the air filter and clean it. A clean air filter is important for two-stroke engines, as it allows for proper airflow and prevents the engine from running too lean.
- Adjust the idle speed. The idle speed should be set to 2,500 RPM.
- Adjust the carburetor. The carburetor can be adjusted by turning the screws marked “H” and “L.” Turning the “H” screw clockwise will lean the mixture, while turning it counterclockwise will richen the mixture. Turning the “L” screw will adjust the low-speed mixture.
- Replace the air filter and start the engine. Let the engine warm up for a few minutes before revving it up. If the engine is running too lean, it will stall. If it’s running too rich, it will smoke.
- Once the engine is warmed up, rev it up and listen for any strange noises. If everything sounds normal, then your Stihl MS 170 is properly calibrated.

What fuel mix to use for the Stihl MS 170?
The recommended fuel mix for the Stihl MS 170 is a 50:1 ratio of gasoline to oil. This means that for every gallon of gasoline, you should add 2.6 ounces of oil.

The 50:1 ratio is the most common fuel mix ratio for 2-cycle engines, but some manufacturers recommend a 40:1 or even a 32:1 ratio for their chainsaws. It’s important to follow the manufacturer’s recommendations to ensure that your chainsaw runs properly and doesn’t get damaged.

Once you have determined how high to set the blade, tighten or loosen the chain tension screw until you have achieved the desired level of tightness.
