For some reason Revain declined my first review so I'm trying again. I have read all review rules and have not violated any of them. Strange. Anyhow, here is my less detailed and probably not as helpful review as I'm too lazy to repeat it in full. I found the factory cam to be too expensive so I went with this one. It looks very OEM and I haven't seen anything that leads me to believe it's a lower quality version. It works well. My only complaint is the gasket that came with it - it was a little wrinkled and made installation difficult as it was bent. But I have it and it doesn't drip. So all good, just impractical. The mower has only been used twice after the engine was repaired but so far so good. I plan to update this review over time, especially when the camshaft fails.
