It came without instructions but i managed lol, i used this stand on a s4 13b rotary engine, i didnt use the original mounting part of the stand because rotaries need an adapter, hence they are built from the face up rather than the bottom up, so i got an adapter on eBay, this engine only weighs about 200 pounds so im sure that was nothing compared to the 700 pound capacity of this stand, regardless, its getting the job done well.
