It's a great deal but it runs hot so your gonna need #1 glow plugs to keep the temp down

Great little engine; very powerful and reliable - except some issues. The pull start is rather weak so I installed the drill starter just to be on the safe side. The stock bearings (7x19x6 mm front and 13x24x6 mm rear) are junk. Replace them with good quality SS or ceramic bearings. Also, get a 3 or 4 shoe clutch in order to get the most out of this engine; the stock 2-shoe clutch is a not adequate.
