Sounds like a head gasket. Start motor and warm up a few minutes, pull dipstick and check for blowback with motor running, if there is any its prob gasket.

There is none. I pulled the dipstick just after mowing for like like 30 minutes, and seen no smoke, fumes or any sort.
 
Craftsman T1200 Lawn Tractor (2014)
Looking up the number it is a Briggs and Stratton Engine.

Nope MTD does not make engines either..

It is gonna be a Briggs or a Kohler If it's a Tecumseh then it's an older model.

If it's a Briggs OHV the model type and code is on the Valve cover. You might have to clean it to see the #'s

It is a MTD manufactured engine in China. MTD has been using a factory in china for engines They oversee the quality control, and assembly, etc. First engines were used on push mowers around 2005, now used on Troybilt,Yard Machine, Cub Cadet, push mowers, tillers, riders, etc. There had been an EFI version since 2015 on select Troybilt, and Cub Cadet riders.

Not Murray, They have to use Briggs engines by contract

Intersting. No wonder I was getting all sorts of weird results for that engine number.
 
Update: installed a new head gasket. and now, no compression. Torgue to 44 ft.lbs. Everything was clean. No problems at all. Adjusting the valves was a little difficult, but after a few adjustments, I ended up with them spot on spec.
 
Your push rods or 1 rod is not in place. You don't have to take the head off to put them back in the right way, just loosen the rocker arms..
