    Atc 70 big bore leaking oil. Help!

    I have an 85 atc 70 that I recently put an 88 cc big bore in. When I started it up I noticed it was leaking oil. If you plug the hole it stops leaking but smokes. What is the cause of this and why is the hole there. It comes from the small hole in the lower corner of the cylinder. Here is a pic Click image for larger version.
