Hello I am just starting to go over my new to me 1992 G1800 (400 hours) and after spending some time with it, one odd thing I have noticed is that when I turn the key off, the engine really slams to a halt without turning over a couple of more revolutions. I have two other larger Kubota diesels, and both of those engines gently (but quickly) stop when the key is turned off, the g1800 almost reminds me of a power tool with a brake that violently stops the tool when power is lifted. Seems to turn over and start ok, runs great, I dont get the impression anything is dragging on the machine, but when i turn the key off (at least when the kill solenoid works, its random) the engine seems to come to an unnaturally fast halt. Any comments appreciated.
