The Mtanlo MS 291 Carburetor Kit is a full replacement carburetor and tune-up bundle designed to restore running performance on compatible Stihl chainsaw models quickly and affordably.

If your Stihl MS271, MS291 or MS261C is hesitating, running rough, or won’t idle smoothly, a faulty carburetor or worn tune-up parts often cause those symptoms. This Mtanlo kit includes the carburetor plus essential service items—air filter, fuel line and filter, spark plug, carburetor gaskets and hose—so you can replace the wear parts and re-establish correct fuel and air delivery in one repair session. Before ordering, compare the parts with your saw’s original components and note that this kit is not compatible with C1Q-S181A or C1Q-S182A primer-bulb models.

How will this carburetor kit affect my saw's starting and idling?
