Clean and Inspect the Block

* Clean the mating surface of the engine block where the cylinder will be mounted.
* Inspect the block for any damage or wear. If there is any damage, you will need to have it repaired before you can install the new cylinder.

Install the New Cylinder

* Apply a thin layer of oil to the piston and piston rings.
* Carefully insert the piston and connecting rod assembly into the new cylinder.
* Place the new cylinder base gasket on the engine block.
* Lower the cylinder onto the gasket and carefully tighten the cylinder head bolts to the specified torque.

Adjust the Valve Clearance

* Use a feeler gauge to measure the valve clearance. The clearance should be within the manufacturer’s specifications. If the clearance is not correct, you will need to adjust the valves.
* To adjust the valves, loosen the locknut on the valve adjuster and turn the adjuster screw until the clearance is correct.
* Tighten the locknut and recheck the clearance.

Install the Cylinder Head

* Place the cylinder head on the cylinder and carefully tighten the cylinder head bolts to the specified torque.
* Install the spark plug wire.

Test the Engine

* Start the engine and let it run for a few minutes. Listen for any unusual noises or vibrations.
* If the engine is running smoothly, you have successfully replaced the engine cylinder.

Additional Tips:

* When removing the old cylinder, be careful not to damage the piston or piston rings.
* When installing the new cylinder, make sure that the piston rings are properly seated in the grooves.
* If you are not comfortable performing this repair yourself, you can take your Stihl leaf blower to a qualified mechanic.
