Been a while since I've timed a CAV/Lucas injection pump, bear with me. If you pull the rectangular cover off the side of the pump (held on with 2 small bolts) you will see the side of the cam ring. It will have a scribe mark on it the you can see move in the window as you turn the pump driveshaft. When that scribe mark lines up with the square end of the snapring holding the camring in the pump body, the pump will be at start of injection. You need to know the static timing mark used for setting start of injection, usually either marked on the flywheel or front pulley, not sure on a 414, but on many engine it is right at TDC. Rotate the crankshaft in the direction of engine rotation, (to take up any lash in the timing gears) until the engine timing marks line up, with #1 cylinder on top of compression stroke. At that point match the marks in the pump and lock her down to the front plate. Turn the crankshaft back 45 degrees and bring it forward again and recheck both sets of marks. Readjust if needed, reinstall window cover plate and bleed pump. Guessing on fuel pump timing and getting too much advance can be fatal to the engine if it is expected to work hard. I refuse to use the external scribe marks on the pump and front front cover, seen them out by over 1/8 inch on a regular basis. Hope this helps.
