backfiring from the muffler. And it's only backfiring when the battery voltage gets low so I am assuming that's a firing issue with the coils and the lack of power from the stator and vr? I torqued the flywheel bolt to 60 ft lbs.

Our local shop is who I called first and they were having issues at the time with availability on the parts. I didn't know if that was because of the age of the mower or just a stocking issue in general from their supplier, so I broke down and searched on Amazon. I justified the Amazon purchase because the parts came from a "small business". I know I may have created more problems by doing that, but I can send most of the parts back. They weren't that expensive anyway so it can be a lesson learned. Could that be the problem? Should I just replace everything with OEM parts Ariens and what I can get from my local shop?
And yes, I blow off the engine cooling fins during the summer season and before putting it up for the winter with the compressor. I try to keep it as clean as possible from dirt and debris collection.
I just remembered that when I removed the flywheel to replace the stator, it was packed with dirt and grass between all the magnets. I took the compressor and a brass bristle brush and got all the dirt removed, but could that cause issues later on? The magnets seemed strong and had a lot of pull when I reinstalled the flywheel.
Should be fine as long as all the magnets are present. Any spots where it might look like a magnet was glued on?
Everything looked normal or at least factory. I've never pulled the flywheel in 13 years and it's never been to the shop for that type of maintenance that required pulling the flywheel, so as far as I know the magnets are attached the same as when they left the factory. Nothing felt loose when I was cleaning it.

Diagnosing electrical issues via the internet is not always the easiest thing to do.
That tells me the ignition timing is off.
Again, check the flywheel key. Make sure flywheel bolt is torqued to proper spec.
Or possible excess fuel or lack of in the muffler lighting off running super lean or rich.

What other have said^^^
People here have on occasion posted that some alternator systems need a near fully charged battery to work correctly. Charge the battery again, and then check the voltage on it before starting the mower. Check it again with it running to see if it is higher or lower.
DISCONNECT the battery when you are charging it just to make sure you don't toast the new VR

The battery is not charging:

Looking at the wiring diagram:
Does yours have the AC ammeter on the dash?
Have you checked the stator output as 28v AC? (this is wire to wire, not to ground)
The case on the regulator MUST BE GROUNDED GOOD to get a charge
If these check ok jumper the red wire from the regulator to the pos post on the battery through a 15 amp in-line fuse. start the engine and measure the battery voltage at high throttle.
Intermittent backfiring might be caused from contaminated fuel.
Does it backfire out the exhaust or carb?????
