Ignition options, I have issues please help me sort my ignition system Options

[CCE]

I installed a CB Performance ignition kit, on my 74 2.0L, with webers. I Have run it for 1300miles +,- and now am in my third coil… it reduces RPM slightly and then, stops working.

Any ideas why?
Like the idea of not dealing with points and condensers, and when working is very nice, but.

Hmm - I’d talk to CB Performance. Their coil is low resistance and low impedance. It will pull A LOT of current. A lot more than a Bosch Blue coil. If they designed it for 1 ohm it’s up to them to make sure it can withstand the heat that it will generate.

Not liking 1 ohm primary at all for use with an old school distributor that has long dwell time (time the coil is energized). Low ohm coils like this usually serve only one or maybe two cylinders (in wasted spark application) fuel injection applications. In your application, this coil is trying to serve 4 cylinders. That means the coil is powered with a whole lot more “on” time than whatever application they took this coil from.

Thank you, thank you, thank you!

It is strange they sell it as a kit. (IMG:style_emoticons/default/confused24.gif)

I will try the pertronix for a while. I have it in hand.
