Please examine this powerhead closely.  These 10hp powerheads were prone to premature wrist pin slop.  So, you will want to carefully/gently rock the flywheel back and forth, using a dowel to check for rod slop before spending too much time on this project.  I too, would leave this engine “as is” on this leg, provided the larger gearcase is in good shape.
