The Husqvarna 266SE chainsaw typically has a compression ratio of around compression 130-150 psi (pounds per square inch) when the engine is in good condition. If the compression is significantly lower than this range, it may indicate wear in the piston rings or cylinder, requiring maintenance or repair. Regular checks can help ensure optimal performance and longevity of the chainsaw.
