✅ Typical Symptoms of Cylinder Wear or Damage: Hard starting, significant power loss, burning oil (blue smoke from exhaust), low compression, unusual engine noises (knocking or pinging). If you experience these issues, the cylinder assembly may need replacement.

⚠️ Installation Note: When replacing the cylinder assembly, it is recommended to also replace the cylinder head gasket. Clean the crankcase mating surface thoroughly and tighten the cylinder head bolts to the specified torque and sequence as per the service manual. When installing the piston, note the direction (arrow usually points to exhaust side). Stagger piston ring end gaps. Allow proper engine break-in after installation.
