Hi to all genius in the forum.
I have a Kubota D640 in a boat. I am looking for advise in how to properly set up screw adjustment behind injection pump? the one that adjusts the rack position.
I am unsure if it is properly adjusted because I was messing with it. Now, under load I get some hunting but only under load and cold once warms up rans ok. I have check the fuel system for leaks, air, etc. I have replace injectors and rebuilt injection pump. I have not checked the injection timing because I just installed with original shims.
Also for some reason this engine when cold takes a few tries to start and also when starts start at lower rpm like 700 and then after a few seconds slowly goes up to 1000 rpm.
Has always done that from beginning not sure why? Any ideas really appreciated.
