Fixed white smoke issue from my lawn mower
Had an issue with my lawn mower blowing white smoke from excessive oil from the crankcase vent. This fixed my issue and I now longer have the white smoke from the mower. Note, the exterior of this piece is not painted, so it will not match the painted crankcase unless you paint it yourself. I personally did not care about the color.

A perfect match for the original part
The part arrived a day early, a perfect match. It took all of 5 minutes to install and the mower started on the third pull. Thanks for the great service. If I ever need mower parts again, your company will be my first call. Thanks again.
