Not the best choice for parts

I have a small motor shop and bought one of these to rebuild a cart. Everything went smoothly but didn't even work for 2 hours. Compression was completely lost, so we did some digging and found that the exhaust valve head had snapped off and gone through the engine. We usually leave these items on the shelf because we see so much, but as I didn't install them straight away we can't guarantee or return them.
