doesn't look like it's rebuilt at all. looks like stock dished pistons, usually they're stamped .030 on the top, etc if it's oversize pistons.
Hard to tell from that picture in the thread. Doesn't look like anything's obviously wrong with it. BIG dished pistons will mean low compression (well under 9:1 with stock 76cc heads) but nothing really jumps out at me being "wrong" with it. Does look like it's been burning some oil as the piston faces are pretty coated with carbon. Have a machine shop check it for cracks and to see what the bore is at (if it's more than 40-over right now I'd pass on it).
