Regarding the coil question;

Most battery ignition quads will have a single coil tube with two coils and two condensers inside. There is also supposed to be a resistor on one end of the coil tube. The resistor knocks the battery voltage down to 6 volts for the coils. If you get better spark on one set of plugs compared to the other, you may have a condenser going sour on you. The coils are usually either working well or not at all. Regardless, you may want to look at emptying the tube out (which can be a thankless, messy, yucky job) and replacing the innards with modern components. Timing will not affect the strength of the spark, but it obviously will affect engine performance if not delivered at the correct time.

Hope this helps.
