Part #530069844
This is an authentic OEM replacement kit for use with lawn and garden equipment. Each kit includes the carburetor, cylinder, crankcase, and muffler gaskets.

If you are experiencing common problems such as leaking, loss of compression, and poor engine performance this indicates that your gaskets may be worn down or damaged and need replacement.
