Thanks Deejay and drjimbeam,
Had another look at it tonight. Rover Model 1507. I will take some pics and post them when the forum is online again in a day or two.
I sort of tested the condenser tonight with the multimeter, and there is continuity of circuit between the case and the centre post - I guess this means that the condenser is bad? Might be best if I replace it if I can, before going down the path of a new coil and points as well. The points look fine.
While I am here - any tips on how best to clean up the alloy flywheel?
I'll keep folks posted with progress. In the meantime, thanks very much for quick responses and the welcome to the forum.
