What would be considered "Normal" compression for this motor, being that it's had moderate use ?
Thanks, Jim

With or without the decompressor operating?
As always, the 2 cylinders must be nearly equal.

Paul,
I don't know. I just purchased this motor and don't know much about it. I've ordered the factory service manual but haven't received it yet. What I did was remove the spark plugs and check compression in each cylinder and they were each 57 lbs. Does that sound right ?
Thanks
