The two could very well be connected. If screwing the pipe into the manifold dislodged a fairly large lump of hard carbon in the exhaust manifold,or if the muffler had a loose bit of metal or rock in it,it may have fallen past the exhaust valve and into the cylinder. A hard bit of carbon,stone,metal can crush ring lands or crack a piston causing just the sort of problem your having. Did you notice a bit of unusual rattle or knock when you first started the tractor??

I had a hard lump of carbon break a piston in a V4 Wisconsin engine. The engine had been running for quite a while when it suddenly knocked a few times,then started to spew oil smoke from the exhaust and white smoke from the breather. Upon teardown I found a dime size chunk of hard carbon imbedded into the cracked dome of the piston. The lump of carbon had come loose from the valve area of the flathead Wisconsin.
