Its been stated already but I will repeat again. Check compression, a low comp cylinder does not require as high of a voltage to jump the gap therefore the spark will appear weaker. A lean cylinder can do this too "lean misfire" Go ahead and check spark by allowing the wires to jump to a ground (not spark plug) they will probably look the same, if not then check cap, dist shaft/bushings, wires etc.
This is the same thing as a low compression engine will not benefit from a high output coil as the spark voltage needed to jump the gap is lower. There might be a small benefit if you also extended the gap of the plug but only if a hotter spark was actually needed.

Today's Featured Article - The Nuts and Bolts of Fasteners - Part 2 - by Curtis Von Fange. In our previous article we discussed capscrews, bolts, and nuts along with their relative hardness and thread sizes. In this segment we will finish up on our fasteners and then work with ways to keep them from loosening up in the field. Capscrews, bolts and nuts are not the only means of holding two parts together. When dealing with thinner metals like sheet tin, a long bolt and
