I think my mistake was reusing the 30yo intake gaskets. I guess my next steps are to pull the heads and decarbonize them, get a new upper gasket set, and a carb kit. The PO had already replaced the coil, points, condensor, and wires.
One thing I noticed when i adjusted he valves was that the intake valve had alot of carbon build up on the stem and underside of the valve. I am guessing this has come from improper timing, or misadjusted valve clearance, or bad valves. I am guessing timimng since it was on both intake valve equally.

The best way to explain is this youtube video I found. It starts with showing how to cut the seats, then finishes with lapping them in. Usually lapping only does the trick.

I told the owner best thing he can do for his tractor is keep it inside and dry.

I have heard of other things, but I won't repeat them as I don't want to sound too redneck LOL.
