The compression release worked before the whole issue started as it would start easy and correctly then and I never took that out of adjustment, so i can't verify unless I actually need to adjust further, but don't want to risk hitting the piston with the valve. I can feel the compression release pushing down on the rocker arms when engaging it though. The chance of water in the exhaust would be slim to none I kept it covered and found no water in the oil when I changed it two days ago prior to looking into the problem for the first time this year. The starter will spin quickly but only when not engaging the fly wheel so I figured that it was working just not turning the engine. Still have to check the grounds on everything though.

when spinning cylinder two by hand I can spin it with one hand feels like little pressure, spinning cylinder one requires quite a bit of effort but never "kick" or rotates more than it should in that sense. On the decompression of Cylinder one it it can be rotated with one hand via socket like cylinder two is at all stages. Also I can hear a "whisping" sound out of the air intake on the head when cylinder one is compressing. Cylinder two does not do this at all. I figured the one cylinder has more compression than the other but don't have the means to actually compression check since he engine doesn't spin over by itself. Then again when I had the head off two days ago I did notice that it still spun over the same way(by hand) with the one cylinder being tougher to rotate through the compression stroke than the other cylinder, and that is with no pressure what so ever on either piston. both sleeves look new, neither has burning or scoring on them.
Yes, rod bearings can. Reading instead of talking face to face I sometimes end up misunderstanding. Just for clarity, are you saying the engine was difficult to turn over when the head was off?

I'm going to toss one more possibility into the equation 
, it might sound imposable but it could happen, You mentioned having the starter rebuilt, have you removed the starter? and try turning by hand? I'm wondering if something went wrong with the starter and the bendix gear is stuck engaged to the flywheel and binding , or perhaps a clutch plate, throwout bearing, etc,etc, can the tractor be put in neutral and pushed any distance? .......... just a thought

As for the starter I have had that off since the issue began and it actually worked fine before the rebuild, but went ahead and had it done. I have had if off since then and it does spin freely and a bench test showed it worked and was engaging correctly.
It took four of us to push the tractor when in nuetral, can't really tell if the clutch is bad. Seemed to work as the tractor has no brakes and we just stopped it by pushing in the clutch. This could have caused excessive clutch/throwout/bearing wear on that end of things though. Wanted to get it running again before fooling with the frozen brakes

I tend to sometimes think outside the box and try to troubleshoot the simplest of things moving toward the more difficult things you seem to have troubleshoot the fuel system and have establish all is well on that part,
I just wanted to bring up some other possibilities before you having to tear into the lower end of the engine, though it does sound like an inspection of the crank and bearings is the next thing to move toward doing
Oh! and also while turning the engine by hand did you remove any belts,? just so's eliminate the possibility of a frozen/stuck alternator,water pump etc,etc,

I thank everyone for their help on this issue. I did have all belt related items off the tractor when turning it. It looks like i am going to have to check the bearings and then the clutch to make sure it isn't hanging, as it can't be budged in nuetral by one or two people, I never thought of that, since I did disconnect the neutral safty to make starting easier while trying to get it started lately.
