I probably shouldn't be sticking my nose in here but I'd say that
while meter checks on a coil are helpful, it is a high voltage component
and might have weak insulation that would short at high voltage even though
it reads OK with a meter. On the other hand, if it does, you will have
pretty clear symptoms - cutting out, maybe only when hot, or maybe not running
at all.

25" is not enough. I have an old rotary vane vacuum pump that doesn't do
any better than that dry but if I give it a shot of oil (motor oil, for
example) in the intake, the vacuum goes up to about 29" for maybe 10-15 minutes.
Some of the old vacuum pumps have an oil injector on the intake that does
this for you.
