Hi All and thanks for having me. I'm really glad I found this forum.
I have a 17.5 B&S Twin motor that runs awesome but it leaks on the left side of the bottom pan. I cleaned it very good and there is no doubt that's where it's leaking from when running. My question is, is it common? I've looked for hours with no luck. I don't think it's just blow by as it runs to good.

Thanks for any help with this.
