Thanks for the info. That's a shame. They seem to be the only ones that are offering the smaller engines along with good prices. I spent many years in South Korea in the early 70's and these little diesels were real workhorses. Seem to last forever. One thing I did notice is they were not used for driving generator heads. They only used them for the 2 wheeled tractors and although they worked them hard you never seen them operating at high speed. Just seemed to lug them at low rpm, maybe that's the secret.
