I wouldn't be too concerned with the chain marks lining up with the marks on the gears, if that's what you're concerned about. Once you crank the engine over, the marks aren't going to be lined up again for quite a few rotations of the engine. The marks on the chain appear to be the same distance from the marks on the gears. Another part of the mechanical timing that you want to be sure of is the crank. Make sure that the crank is in the correct position as well. If all three of these line up, then your problem is not with the mechanical timing.

My personal opinion would be to start checking all of the electrical in the ignition. Step one, make sure you have spark. If not, figure out why. If you do, make sure that your distributor is timed correctly.
