My Ruby is going again now. I mentioned in my modified original thread that I had replaced the contact points to attempt to correct slight misfiring. The old points were set at 25 thou gap. I set the new points at about 12 thou gap because that was recommended in the Austin manual. This is when the trouble started.
I checked the points gap a number of times during all my fault-finding steps and they continued to be in the region 10-12 thou. But the performance of the engine was worse and worse with every start until it wouldn't run at all - just gave a few backfires.
Today, I set the points gap to 25 thou and hey presto the engine ran well. I ran it for more than 10 minutes in the garage before turning it off.
When I pluck up courage, I will take it for a long run to confirm that it is all sorted.
Unfortunately it still has the original slight misfire. I will run with that. This could be a case of not seeking a perfection for sake of reduced stress.
Thanks for all the helpful comments.
Regards
Graham.
