||Engine has been rebuilt.Head reworked.Injector pump rebuilt and injectors checked for spray pattern. I've got the glow plugs working and I still have to give it a wiff of starting fluid to get it going. I have checked timing and valve adjustment. Still a little hard to start after it has warmed up.I don't have any visible fuel leaks. Any ideas???
||I would take another look at the timing, it may appear to be ok but the timing gears may be one tooth off during assembly of the engine. I have seen this happen before, and the only way to be sure is to remove the timing gear cover in front. Frank, Holz Equipment Service
||When they reworked the head, did they check the valve recess? I have seen situations where the valve seats were ground and the valves sit lower in the head. This can cause a slight decrease in the compression ratio. Lower compression will make it start harder. If the head is thick enough you can plane a bit off to reduce the valve recess.
