Very sorry to hear about your wife. I will add you to my prayer list.

I would take the carburetor off and thoroughly clean it. Same for the distributor - make sure no vermin have chewed any wires causing intermittent grounding. Clean the points and check for correct operation. While I was doing those things, I would put some MMO in each cylinder and let it soak for a day or so. Then I would try to run it from a lawn mower gas tank or something similar gravity feeding fuel to the carburetor.
