Yes, the spark should be vivid and noticeable. Generally, you should be able to get a solid 1/4" arch when grounding the plug to the exhaust manifold or block. Did you check each plug for start during the starting mode or only one? Sometimes, that little spring loaded terminal loses it's "springyness" to make contact the rotor button. Have you already replaced the cap and rotor too?
