Thank you, I checked with oldInternationaltrucks.com and they have starters for about every International engine there is- except the 401. Same for carburetor kits, I didn't see one listed for the 401 engine. I've rebuilt a starter or two myself, and generators too. Pretty easy actually, but you still need the parts, like the brushes, bushings, etc. But when it comes to carburetors- I'm afraid to touch 'em.
There's a place in Roanoke that I got a positive ground alternator from for a B53S Mack I used to have. I called them and asked if they could rebuild the starter and they said "absolutely". So I'll probably just take it off one day and take it up there. I don't remember how much they charged for that alternator, but I remember that it was much cheaper than I was expecting it to be.
There was nothing wrong with the alternator until someone was putting new batteries in the truck and forgot that it was positive ground. I- I mean they- touched the cables to the wrong post for just a second, and that was all it took. Fried.
