Champions do better as a fishing sinker than in your engine. I like AC Delco Autolite or NGK, or Motorcraft in a Ford. Only problem is at some point in time Champion makes plugs for everybody. Just depends on who needs what and what they're tooled up to make.
That said, you've got either a condenser or coil breaking down. Either upgrade it to a Pertronix and Flame Thrower coil or use Standard Blue Streak from our buddy Steve in NJ.

Do a compression test, you may have a weak engine. Trev.

I think when you get to the wires you'll have found your problem.

another little tidbit......  check the cap and rotor... If the rotor doesn't make really good contact you will have a weak or no spark condition. I have one rotor that's a cheapo and nearly every time I go start the tractor, i have to bend it out to touch the cap. otherwise it won't start or runs poorly. I bought it that way, cheap...

Have you checked the timing yet? I was going to suggest it before, but someone else already had.

I have adjusted the timing 4 times but just by ear I just try to get the fastest and the smoothest and then retard it a bit. I don't know how to do it with the timing light.I noticed it has a slight seep of coolant coming out the head gasket on the sparkplug side of the motor.son of a biscuit

They seems to be how everyone on here says to time it by year, unless you're using a timing light. Is it seeping coolant or oil? The pushrod oil galleys run very close to the edge of the head on the spark plug side and tend to seep oil.

Take a look here if you what to see the head off.

It was coolant green n clean but no coolant in the cylinders looks like there might be a bit of oil in the 2 cylinders that r fouling out. Does this sound like it could be the root of the problem. Seeping ecsess oil into cylinders and fouling plugs

Plug in the wire that goes from the top of the coil to the distributor cap. Support the other end 3/8" from the ground terminal. Connect battery voltage positive to the positive terminal. Connect the battery negative to the negative terminal temporarily. Every time you break that connection there would be a spark across that 3/8" air space. Without a condenser it will be yellow. With the proper condenser across the connection you break the spark should be blue. Be careful to not contact the high voltage parts with your body, it will HURT big time. There can be enough voltage on the circuit you break to shock too so be careful use insulation between you and that wire.

I'll put my 2 cents in also. I had a WD and it had the similar problem. I changed the spark plug wires and problem solve. It backfired when under load also. Also different spark plugs.
