Looking at a Running Honda GX620 V-Twin 20 horsepower engine. Side of block has a crack that has a temporary repair behind the starter (see picture) Engine Runs great and while the temp repair is holding well, I strongly suggest that the crack be welded by a professional and repair area is easily accessible by removing starter and crankcase cover.
No other damage on/in block when rod broke. Engine is also needing an external piece for the governor.
Engine has New gaskets, Rods, Pistons, and rings.
