My B won't turn over!

I put it all back together and it's doing what it did the first time, turns over easily with the plugs out but not easily with them in. I tried the starter and it will turn it over twice with the plugs in then stops.

It is building pressure but the starter won't turn it over more than once or twice with all of the plugs in. If I remove one plug, it'll turn over fine with the starter... Doesn't matter which plug I remove. Also, even though I've rewired it and have power to the coil, it doesn't have any spark.

Did you use heavy enough wire for the battery cable? 0 or 00, no # 2 or lighter.

A lot of good advice here. I would try the following and if it doesn't work then you can sell it.... If ever you suspect water/coolant in motor, drain oil out first fully, refill with good oil, you may see how much water comes out from the pan and may be able to save the oil while it runs a while and then change it and filter later.
The rings likely stuck from water in exhaust or condensation.(once its fixed again, best to start it every couple months or so....
best way to limber up is to use pb blaster or seafoam in spark plug holes and let it soak. use a half a can+ on all 4 cyls. If you drained the oil all out plug the pan now. keep plugs out. next remove rocker cover. let sit a day or two.
next crank engine over by hand and ensure all valves move up and down well when you do so, look for a stuck valve, some left over lube might come out plug holes, if it turns easier then drain pan again add new oil and crank with the starter plugs out. if still stiff, you could spray more blaster in plug holes with oil in pan and tow it around for a mile or two till it loosens up.
the spark issue is probably corroded points or bad ground to points?,with key on use a screwdriver to open.close points while seeing if you get any coil spark... it could also be your coil....if you get some spark, try to clean them up or get a new points set. some people never say to wire wheel or emery cloth them... hey if it gets you spark you can replace them later, I like bead blasting them myself. good luck,
pound per pound one of the toughest, best tractors ever made.....
sounds like you are in a humid area that has a lot of dew...

Just for grins and giggles, look inside the inspection hole for the clutch. Mice can drag in an unbelievable amount of stuff if there's enough of them. One good big mouse condo could be preventing the flywheel from turning easily.

Jumper cables

I say starter is the trouble. My 8N was that way, then one day it just gave up the ghost. $20 later I had it rebuilt and to this day it runs like a new one! There was about 1/2 cup of dirt and corrosion came out of the thing when I took it apart. I put in new brushes and springs, and polished the armature a little bit.

I repeat, forcing a stuck engine over is a proven way to bend a connecting rod sideways that will add binding of the piston and the rod bearing leading to breaking that rod when running and the broken end of the rod often bashes a hole in the oil pan or block.
