REBUILD / PORTING CANDIDATE

The cylinder bore has been inspected and the visible marks in the bore do not catch a fingernail when checked by hand.

There is some damage/roughness around the transfer-port areas, as shown in the photos. This may be of interest to someone rebuilding or porting one of these cylinders, where the transfer ports can be properly inspected, cleaned up and potentially blended/enlarged as part of the porting process.

I am NOT representing this cylinder as ready to install.

The cylinder should be professionally inspected, measured and properly cleaned/reconditioned before use. Buyer should determine whether the existing transfer-port damage can be safely corrected during the intended rebuild or porting work.

Used OEM condition with normal carbon, discoloration, scratches and surface wear.

Includes:

• OEM cylinder

• Cylinder bolts shown

• Intake component shown attached

Please study all photos carefully. You will receive the exact cylinder shown.

Please verify the OEM part number and compatibility with your specific chainsaw before purchasing.
