ballast resistor, weak spark, etc

[joe brackin <joebrackin@attbi.com>]

Does anyone know what resistance the ballast resistor is supposed to be? 
Mine seems to be about 2.5 ohms when cold and goes up to about 5 when 
hot(which I think is part of my weak spark problem). If mine really is bad, 
has anyone found a source for replacement?
I have switched to a pertronix ignition and coil, but I'm still suspicious 
of the resistor. And finally, can I just remove the resistor now that I'm 
running a coil with internal resistance?
Thanks,

Joe
