Ignition Question
#3
It is a Pro-Spark. they are no longer in business. A C/H can be used to replace it. The timing for the ProSpark was set a 5 degrees BTDC. If you replace it with a C/H auto advance you should set your timing to 28 degrees BTDC.
The ProSpark also had a coil that was attached to one of those leads.

C&H...About $20.00.....Be aware
Pro spark ignitions have been known to die when tested without grounding the spark plug..The spark goes back through the circuit and burns up some of the components...
That might be why there are no more Pro Sparks....Jerry Nelson Hobbies was one of the dealers, might have some insight.....
