Ignition timing can only be off if the reluctor ring slipped on the stub shaft or coil wires are crossed up. Pull the primary clutch and stub shaft to check the position of the reluctor ring.
These are interference engines so if the valve timing jumped on the cam gears then valve/piston damage could occur. If that happens the engine wouldn't have good compression. Off by a tooth on the gears it should start but not idle properly. Rotating the engine in the reverse direction can cause the valve timing to jump. Check the timing marks on the cams and flywheel.
