Hi,
When I realized I had been a dummy there - talking about specifics for the wrong model - I was going to edit them. But, then I thought (I know, Dangerous) I would leave them. The title of the thread is not specific to any given machine, so someone with a no-spark issue will find it easily. And, at the rate we're going the information will soon cover any spark system there is out there!
I will now add the 'why' for the condenser. Which, in electronic terms, is known as a capacitor.
The pulsed nature of the ignition means we are actually talking about alternating current. Direct current is converted to AC by the action of the points. The coil is a step-up transformer. And, transformers are an AC-only component.
One item to always consider is that in an AC circuit, a coil shifts the energy in one direction, and a capacitor shifts it in the opposite direction. So the condenser is there to bring balance the force. Better than Anakin Skywalker did, anyway.
If there is no balancing, as in no condenser, then the backfeed voltage from the actual spark will cause another spark - across the points. That, then pits them quickly.
But for testing, one can disconnect the condenser and be OK. Sometimes the condenser isn't right in some way and can make for a weak spark.
One thing about a weak spark is it may spark out in the air and not under compression. But, one can tell by how fat the zap looks with a test plug.
