IF..the crankcase breather is working, I've got another theory. What if 
the thing is putting fuel in the crankcase and it exploded? Seems like 
in one post all you added for the propane conversion was a piece at the 
back of the carb and then in another post you said something about new 
carb. If the crank is getting super hot without the pump attached, I'd 
say theere is a problem there somewhere. Doug T
