If the engine is turning smoothly it lookes like you got them right! Set the flywheel or wyway on the crank sprocket to TDC on the number 1 firing stroke. Both valves should be fully closed. If they are rocking you are on the wrong stroke. Even if the pump markings are a couple of degrees out you should at least get smoke up. The ring is fixed so if you cannot align the mark the timing may well be out. If you have to check it you will need to reset it unless you have the patience to keep turning until it lines up. Assuming that the fuel pump has not been overhauled it is not uncommon to have to tow the tractor to get smoke up and eventually start. Slightly higer cranking speed makes a difference. Slacken at least two injector nuts off and turn the engine until you see fuel dripping/spitting out. Tighten up and you should at least get smoke at next try. Try not to use starting fluid.

If you are getting some smoke then at least its trying to start albeit with the timing out perhaps. What I think may have happened is that one or more of the gears may be one or two teeth out. The only way to be sure is to remove the cover and reset the marks. The annoying thing is that you will not know if they were wrong until you try to start it again. But you WILL have the satisfaction of knowing that they are correct NOW. When the gears are correct then if it does not start its not going to be a timing issue. As mentioned in my other post we have had instances where we failed to start after a rebuild where the pump was not overhauled and had to tow to start. Avoid using a chain though.
