Can't see any reason for 2 condensors in the one system. Maybe one failed and a replacement fitted elsewhere and wired in place there. I have been using film capacitors instead of condensors over the last couple of years. These are more reliable and can be very small in size but big in capacity so they can be fited almost anywhere. I prefer the ceramic ones over the plastic ones just as a heat shield issue. Try using one with values of 600V and 0.22Mf. No positive or negative sides just insulate one side going to your points with plastic or shrink wrap.

Thank you cobbadog for you help. The second condenser was attached outside the breaker box. I dont remember who/when I had work done on this engine last. It has not been in use for the past 8 yrs or so but did not run correctly when I tried to start it.

Anyway I ordered new points, condenser, and coil and they sent a condenser that matched the one that was attached to the outside of the breaker box.

The engine does not run with the inside condenser removed from the circuit so I am going to replace the coil now and take the cost hit.

Hopefully the pic got attached.

Good news that you have resolved the mystery about the extra condensor. Interesting in your picture that both the points and condensor look very similar to those used on our very early Victa 18 lawn mowers. Those ignition parts were made by Wico out here.
