It is a 1949, and while you can certainly try, you are NOT going to find a rebuilding kit at the local parts store.
And Greg, no offense meant to anyone, you or the gentleman from whom you purchased the truck. It takes only a few minutes to do a compression test. Then you know. If you have just one sticking value, NOTHING that you do to anything else is going to fix the problem.
Don't take someone's word for anything....test it.
Every single used car I have bought in the last 52 years had a "rebuilt engine within the last nnnn miles", even the ones that hadn't run in 20 years (just rebuild before we parked it)!
My checklist should be done in order, as the later items will not fix defective items earlier in the list.
Jon.
