Hello we have a b7100 new style. Just rebuilt, new sleeves, pistons and rings, all bearings, head gaskets. new valves, valve springs, seals etc. Got it all back together and was very hard to start, lots of cranking and bleeding fuel system but finally ran but seemed off. It now starts after 45-60 sec of glowplugs but runs rough with smoke out of tailpipe, won’t throttle up and then dies. I am looking for some advice on troubleshooting this.
So far we have attempted to check the fuel injection timing but this flywheel does not have the FI as stated in the workshop manual? Only TC and 20-0 degree marks. The injection pump has 3 shims one thicker and two thin ones. We removed a thin one and it will not start at all, just coughs a little but no life. Verified glow plugs are good 1 ohm each with 10.6v to them while energized. Valves were adjusted to .009 when engine was assembled. Engine rolls over very smoothly, all dots on the front timing gears were aligned when reassembled. I’m sure I am forgetting info but I am leaning towards a missing shim somehow or valves could need readjusted. Any ideas? Has brand new fuel filter and getting plenty of fuel, no obstructions to pump
