don't do as I did when having the same problem as you, spent a lot on mag refurb only to find out  later it was the points that were duff and not the internals of the mag

I suppose that a failed condenser also has an influence on the points lifetime or am I wrong here?
Always thought the condenser was there to prevent the points from arcing when opening and closing or isn't that the case on a maggy?

'Tis very much the case morris, and arcing will eat into the points quite fast if it starts. I guess that's why in the old days when you bought a fresh set of points for your typical family car every few thousand miles, many routine service kits came with a new condenser, whether it was needed or not. Happy Days!

 Apart from any A10 magneto issues, or only ever had two condensers conclusively fail- one on the Hilux and one on the Gutzzi,  but don't remember ever replacing one before that..... but they both needed them big time
