Not firing, Bad rings.  Could be a bad plug wire, a bad plug, stuck valve and maybe wrong firing order.  Is the firing order correct?  You should have 2 fouled plugs though if this were the problem.  Get another plug and try that.  Then try a new wire.  Or do both if you want.  How long does it take to foul it out?  When was the last time you changed the plugs?  The wires?  How good is your spark?  Could be weak points and this plug is the first to foul?
TOO MANY unanswered questions to positively help you.

Bad rings, valve guide gone or a valve not seating good can all do it. My CA sat for 10 years and then another 10 years after only being run a few hours. It fouled a couple plugs in less than 4 hours mowing time. I put  a one set hotter plug in and ran the whole mowing season without cleaning a plug. I believe the rings were stuck and not working and freed up with heavier use and some Sea Foam.
 I wouldn't want to guess what your problem is without knowing some history of the tractor.

Champion plugs? They tend to not clean up when the engine is running right. Only new plugs like AC survive well these days.

 With that info, here is what I would do. Replace the plugs with Autolite 295 or equivalent. Do a complete tune up with wires, points and condenser. Make sure the gas tank is clean and sediment bowl is working with a good screen. Fill it up with good gas and add a can of Sea Foam. No go out and make it work. You don't have to plow with it, just work it somehow. Might take a couple tanks with sea foam to loosen things up. If it keeps fouling plugs check compression and determine if your plug cleaning time and oil consumption warrants a complete OH of the engine. JMO

I would change one thing at a time.  All of us have seen a NEW set of points, a NEW condenser, New plugs wires, etc. that are BAD RIGHT OUT OF THE BOX.  Take your time. Change one thing, make sure it starts and runs and then change the next thing.  You can change ALL of the plug wires in one setting, just make sure you do ONE AT A TIME.  If it misses, you can pull them one at a time to see which one and then replace that one.
When you do them all at once and one of them is bad, you have to do a lot of extra work to see which one is the culprit.  Do em one at a time.

A quick cheap check would also be to pull the rocker cover and do a quick check of clearances. If you have no clearance in one valve, you could be sucking oil down thru worn guides. i guess a bore scope might be handy too in case a valve has a lot of carbon build up but, working it with Sea Foam in the gas will help clean this up as long as the valve has enough clearance to close and it seats OK.

Mike, do a compression check.  If one cylinder is much different than the others, you know where to look.

I picked up a D15 SFW earlier this year as the price was right and I only wanted the SFW assembly. Thought I might have a decent 149 engine to rebuild for my stuck CA. Ran a liitle rough and had some smoke, the oil filter actually was rusted on the outside and the ol' boy I purchased it from had not used it much the last three years. With nothing to lose, dropped the old oil/filter and Seafoam'd her in both the engine and the fresh gas I put in her after servicing the sediment bowl. Put her on a 6' brush hog and worked her hard for a couple hours. Dropped the oil and replaced same with a new filter. No tune up parts as yet and she is running well so maybe I had a ring sticking.
I treat everything I pick up with Seafoam, but do not leave it in more than two hours.
New oil changes all get 1/2 to one cup Marvel Mystery Oil.

Agree with Tim.  Sea Foam the gas and oil and run her a few hours.  You can also use ATF in the oil with like results if it's a sticking valve or ring.

Well that's not good with it burning oil and antifreeze.  Sounds like a bad head gasket also.

nevetheless as advocated above just running them for a short time with lots of lubricant allows a lot of machines (not just engines) to sort of "self-cure".  at least partially. then it's easier to see what really requires fixing.
good luck & don't be in a hurry.
