Kingtech is also cheaper in price. New KT pumps also self prime before start.
The 140 JM is nearly 1 lb lighter than the KT. Brushless on the JM doesn't do much for me- It will last longer, but is more expensive. For a flash I would go for the lightest weight install. The new KT pump self priming valve on the pump doesn't do much for me either.. just something to clog/plug and cause an issue. with the old pump if get some air in the line it might not start the first time.. if the purge valve screws up on the new one you are potentially down for service..
The ability to run diesel is nice.. I am sure the JM would drink ok it but they don't recommend it so whatever that is worth.. I like to be able to dump my fuel in the tractor if gets too old...
