Install new condensers and see if things improve.
Condensers are cans with coils of metal foil and insulating wax paper or later mylar film
Capacitors serve same purpose in electronics. If desired a
capacitor can be installed inside condenser can for original look,
Rating in Micro Feraads (sp?) is about the same value.
Coils can look bad and be good
or loook good and be bad. They can also start and run for a while
and quit, A friend rebuilt magnetos for antique engines and he ran them in on a test rig to see how they behaved once warmed up.
Upper crankshaft seal is often the one installed at factory and is leaking. Magnet rotor has to be removed to get at seal Can be done without service tools if you are gentle and do not pry or hammer,,
Good Luck
