With cross-hatching still visible, there are probably only a few hundred hours on on either the new or re-honed (or rebuilt) engine. Unfortunately, the carbon deposits have caused an undue amount of scoring. Visually it difficult to tell the depth of the groove wear. Can you catch a fingernail on the grooves? To really evaluate things, the cylinders should be measured to judge whether they have been re-bored, or if maybe out-of-round cylinders were just honed. If oversized pistons have been used, they will be marked on the top. Are there rust spots along the bottom of the cylinders (from water setting in the engine) or just specs of dirt?
