I recently joined in the ownership of a Kubota, 1998 B2400 that I knew had some issues, had to replace starter, fuel pump and am trying to get it running. It turns over good, fuel at injector seems weak to me (been a few years since I worked a diesel) fuel only lightly squirts out, anyway it try's to fire over with white/gray smoke from exhaust, but just won't hit. My question is it not getting enough fuel or maybe low compression? Thanks in advance for your help.
