I do have a few donner machines and would have a coil. are you aware that you have a separate capacitor to enable this coil to work it is normally located just under the off switch.
these are the part that tend to fail and stop the coil from being able to work I would have some untested ones but obviously couldn't guarantee they would be in working order.
I started on the blades this week check them to see how balanced I had them just need to file some of one of them the other to seem ok
