I'd bet it's a timing issue. Probably too early. Black smoke is early, white is late.
I also bought a kubota project last year. It had chewed up most all of the timing gears. After replacing all that, it ran, but not good at all. I swore it was missing pretty consistently on one cylinder. Took the pump and injectors in and had them gone through. Same deal, same cylinder. Had pump shop recheck and even had the guy come out and hear it run. He agreed. After the third try on the pump, I started removing shims from under the pump(advancing the timing). The more I pulled, the better it ran. It's actually running with no shims now. It starts easy, doesn't smoke, and runs good.
I'm not sure if the whole timing gear deal may have slightly twisted something throwing the timing off or if it was that far out of whack prior. The pump had been messed with before as it had newer paint on it.
I'm thinking your issue is timing is too early. I'd guess you need to add some shims under your inj pump.
Jm is the resident kubota expert. He can probably say for sure. I know he pointed me in the right direction.

The discussion started out with the following post: "I have an aluminum steering gear housing with a bolt broken off in it. The bolt is about a 3/8" x 1 1/2" bolt. I've already drilled the center of the bolt out with about 7/64" drill bit the entire length of the bolt. Only one end of the bolt is visible. I tried to use an easy out but it wasn't budging and I didn't want t
