New Member with Question about Yanmar Diesel

[lateral]

there will be a bar running vertically see if if wiggles fore/aft easily with extra light pressure. If so, the rack is good.

The vertical bar in the pic is locked solid. Would this have anything to do
with 2&3 not pumping?
Am I gonna have to pull the inject pump?

Looks like a removal of the timing cover (per Tom & Jills) method to inspect fuel shutoff/govenor arm/fuel rack system to see what is stuck. Seem reasonable?
Should the timing case have black tarry looking residue throughout, as shown in the pic's?
