      That seems low to me. I would look for another. Maybe someone with more experience with these will chime in.

        I’m not sure what range of compression figures this particular model might typically have, but 105 sounded low especially since the seller says the cylinders have been honed and new rings installed. Suppose it might get better after the new rings get seated better. I’d appreciate any other input anyone can offer on this.
