Hi Bruce
The spark is very faint but it is more yellow than blue. I have cleaned the points and although they are a little pitted they are clean and gapped correctly.
By the MAGNET do you mean the inside of the flywheel???? It is clean (ie no dirt or rust) but it could be polished with metal polish if that would help??? I'm not sure of the condition of the condenser..plus I am in the UK so I might be struggling to get one anyway :-(
Thanks for your help!
