Trial and error with diesel fuel
systems is not good practice. It works fine with gasoline engines pre electronic ignition. I can easily set timing and gaps for anything old and tune it by ear. Not so with diesel
You need to use a dial indicator on the valves to find TDC. You then need to either find or add the corresponding injection pump timing mark. Do it once and do it right. Is it really missing?
You can use a center punch to make the mark and label it in situ. Of course I'm assuming you have the right pump and the drive gear
is correctly installed. There are two options from memory. I have a cav unit.
