[Spridgets] New Problem

[David Lieb]

Sounds like you finally found a legitimate use for one of those 
spark-testers. Either you have defective plugs (LOTS of them!), or there is 
something about the spark that just ain't right. Have you done a compression 
test? Have you tried cranking it over with the sparkplug against the engine? 
Are you running points? Have you checked the coil to see whether it expects 
a ballast resistor (resistance across the primaries with at least one side 
disconnected from the car should read about 3 ohms, if it is around 1.5 
ohms, it expects an external ballast)?
