how to adjust a stihl ms 251 carburetor?
Step 1: Determine the Carburetor Type
Before you begin adjusting the carburetor on your Stihl Ms 251 , you need to determine what kind of carburetor you have. Your Stihl chainsaw may have one of three types of carburetors: fixed jet, adjustable jet, or a high-speed needle valve carburetor. Each carburetor type requires a specific adjustment process, so it’s essential to know what type of carburetor you have. You can find information about your chainsaw’s carburetor type in the owner’s manual.
Step 2: Locate the Adjustment Screws
Once you know what type of carburetor you have, you need to locate the adjustment screws. The adjustment screws are usually found on the side of the carburetor and are typically marked with the letters L (low-speed fuel mixture), H (high-speed fuel mixture), and I (idle speed adjustment). All Stihl chainsaws have these screws, although their location may differ based on your model – again, check your owner’s manual.
Step 3: Adjust the High-Speed Screw
After you have located the adjustment screws, you can move on to adjusting the high-speed screw. Begin by starting your chainsaw and letting it warm up for a few minutes. Once it’s warmed up, adjust the high-speed screw by turning it clockwise until the chainsaw begins to sound rough, then slowly turn it counterclockwise until the engine runs smoothly. If your chainsaw lacks power at high speeds, you can lean this screw out a little more to increase your chainsaw’s performance.
Step 4: Adjust the Low-Speed Screw
Once the high-speed screw is adjusted, you can then move on to adjusting the low-speed screw. Adjust the low-speed screw by turning it clockwise until the chainsaw begins to sound rough; then, slowly turn it counterclockwise until the engine runs smoothly again. You can check how well the engine is running by revving up the chainsaw a couple of times, confirming that the engine doesn’t stall or cut out. It should idle smoothly at a stable RPM.
Step 5: Adjust the Idle-Speed Screw
Finally, you can adjust the idle-speed screw. This screw controls the idle speed of the chainsaw’s engine. The idle speed screw is located near the air filter system of your Stihl chainsaw. It’s essential to ensure that your chainsaw is at normal operating temperature before attempting to adjust the idle-speed screw. Adjust the screw by turning it clockwise to increase the idle speed or counterclockwise to decrease it until you have the ideal idle speed. The correct idle speed is necessary to keep the chainsaw chain from rotating before you hit the throttle and ensure the chainsaw is running properly.
In conclusion, maintaining your Stihl chainsaw’s carburetor is essential, and adjusting it regularly will help keep your tool in good working order and ensure efficient performance. Follow these steps, and you’ll soon be an expert on carburetor adjustment for your Stihl chainsaw!
