Up for sale is a K341 engine block that was removed from a John Deere 316, will fit the 300 and 216 as well, dipstick may be a little different.  Engine ran good prior to removal.  The points will need to be replaced, engine may need throttle adjustment wasn't quite right, did run good though just seemed to not have a good movement from throttle cable seemed to be on low idle for most of the throw of the cable then high right at end, worked, but wasn't quite right may have been cable or may be springs possibly governor.  Take a look at photos, to make sure if will fit your application.  I do my best to package this well, but ups is rough and it is an extremely heavy engine, there may be some damage to the engine tins.
