Your Marelli was produced in a range of sizes. They carried model numbers like 0.40. 0.35, 0.30 and I believe 0.25 in decreasing size. Not very catchy model naming system eh?
The "brushes" are certainly oiler wicks heavily charged with dirty sediment laden oil residues. Your starting and running problems seem almost certainly due to lack of oil...20 years! A tribute to good engineering it didn't seize up long ago.
I have been constantly amazed at how you can bring oiler wicks back to life. Soak them for several days in a good solvent I use paint thinner but there are several solvents which will do the job. They never recover their original offwhite colour but will become supple again and have enough remaining capillarity to do their job of passing miniscule amounts of oil regularly to the bearings.
You might want to consider taking the back off the gear box and changing the grease as well. I imagine that that is hard crusty and deep brown by now. This will dramatically reduce the drag on the system. Do not overfill the gear box as it will swell up and leak out. About half to two thirds full should do it.
These Marellis turn up here quite regularly so if you need any parts and can't find them in the USA send me a note of your model number (I guess 0.40 or 0.35?) and a picture or solid description of the parts you need (if you can guess what's missing).
