Yanmar 4JHE resurrection

boat is new to me (Freedom 39 Pilothouse)
engine has not been run in 3 years (until last week)
Yanmar 4JHE, normally-aspirated 4cyl @ 44hp

knocking and smoking a bit, but up and running (took a bit of work)
fuel and electrical supply are OK, new filters etc
videos from yesterday:

need to check/adjust injection pump timing
PO had a guy remove and service the IP, and engine 'didn't run right' after he reinstalled it
I am guessing he did not re-time it after re-installing

also want to make sure valves are good, and head bolts re-torqued, before sea trial
she is on the hard up in NH

questions:
1. anyone done IP timing on a 4JHE?
2. anyone done valves?
3. head bolt re-torque?
thoughts on any of those procedures?
experience with white smoke? pronounced knock?

any suggestions much appreciated
thanks!

Rolf in MA
