SEMTO Engine ST-NF2 DIY Mini Metal Engine Kit, L2 Inline 2-Cylinder Air-Cooled DIY Engine with Starter Kit, SEMTO Engine Model Kit That Works for Adults

The instructions were incorrect and parts were miss labeled

I have bought and built several of the Stirling/Semto kits and they are marvelous, intricate, and high quality. This one was good but not without problems. The instructions were not as clear as in the other kits, and while not impossible, required study and in one place, figuring out that a bracket attachment was not covered but needed to be done next.It was missing one piece - but I managed to make a satisfactory substitute, although not without some trouble. But in addition heat bolts would not fit through the holes in the head casting and I had to drill them out sightly, something that concerned me but worked well (fortunately I had just the right width drill bit). Overall I think I got my money's worth, but someone with less experience might be frustrated by the "noise" in this product.
