Platinum 24 starter woes

So I have a 3 year and 1 month old Platinum 24 (921028), I added the 1 month as the warranty is good for 3 years on the engine so it's just past and I've already contacted Ariens who at least responded but weren't very helpful. Electric starter spins and doesn't appear to engage the flywheel to spin it over. I took it off and cleaned up the bendix thinking maybe they used an improper grease or too much causing it to stick and relubed with graphite. Bench testing it worked perfectly. Bolted it back on the snowblower and tested before reassembling everything (stupid design to access starter bolts but thats another story).

After everything was back together, back to square one. I tried a different cord (14ga. 10 ft. cord USA made) since I was using a cheaper cord previously which seemed to work initially but fast forward a couple days later and same thing. I would just buy another one but it seems to be sold out/out of stock everywhere which leads me to believe this isn't an isolated issue. By the way, thanks Ariens for wanting to charge an $80 premium on top to have your part no. for the starter.

So venting aside, what else can go wrong with a starter to cause this issue?

So during bench testing the starter gear extended out to its working position and spun?

Yes it did, I think that's why I'm so baffled. Now that it's fully assembled again I can't see what's happening. I can disassemble again, which I'll need to anyway, but I'm afraid it will be one of those can't duplicate it when you can see it scenarios. Maybe not but I'm a bit frustrated with it at the moment.

Maybe the bendix is slipping, like the Ford starters did back the 70's.

I don't get the Ford reference since I was born in 69 and didn't start working on cars until the 80's. I did notice that there is quite a bit of slop allowing the bendix assembly to move back and forth. When I say quite a bit I'm meaning enough to hear it if you shake it, maybe in actuality a 1/16 or less. I didn't measure it so this is just throwing a number out there but I'm not sure if this intended by design or not.

Slipping... the bendix extends and engages the flywheel teeth. The starter armature spins, but the bendix drive slips and does not turn the flywheel.

The bendix is a one way clutch, if this simple starter uses a bendix. Could be a fixed gear.

So I took it apart again and observed it closer this time. When the button is depressed the gear extends fully as it should BUT it then retracts about a second later. The shaft still continues to spin so the only thing I can think is it slows down enough to not keep it extended. Not something observable by eye but the only thing that makes sense which would mean the motor itself has issues. Guess I'll be buying another one whenever they're available. I really miss my old Yard Machine blower, 15 years old when I got rid of it and I only had to change the oil and grease on occasion. This Ariens is a new problem whenever I go to use it, going to have to buy another blower to have as backup since this thing is so unreliable.

Lets take that one step further, if that were the case the flywheel would at least begin to turn. Something else is still going on. In any case the starter no load RPM is probably not representative when in actual use?

You could see the flywheel bump when the starter was engaged but definitely did not turn it by any appreciable amount. Anyway, found and ordered one last night at the low cost of $190....yes that's sarcasm. It is what it is I suppose.
