At least that is what's on the shroud. Shroud says it was made for noma but it's in my elderly neighbour's poulan.
Whew brands rather convoluted... It started with , if I recall, Roper, then became American Yard Products which bought Weedeater (which bought Poulan) So Roper/AYP/Poulan/Weedeater which then were all bought by Electrolux AB , which finally became Husqvarna , split away to Husqvarna Outdoor Products (Husqvarna's consumer brands) Noma (Formerly Dynamark) was also purchased partly by AYP (and other parts by Murray Ohio which then became Briggs Outdoor) So, makes sense to see a Poulan listed as being for "Noma" (or AYP or Husqvarna) Also note I may have the "who bought what" order wrong (I remember when Dynamark, Roper, Noma, Murray, Poulan, Weedeater were all their own completely separate unrelated companies competing with each other...So, memories can get foggy over time.)
Her son said it was running wouldn't start. My first test had a very slow crank on dead battery and booster. I told him to charge/replace battery. He says he charged it and still not cranking good and burning and smoking. I tried with new battery, same thing ,flashes of light below starter. So I pulled starter which was standard with a plastic gear. So I put on an old used and it starts fine with his battery and verified charging works. So now I'm home looking up starter price and found ipl says it has steel flywheel, so I'm assuming starter gear should be steel. Ipl shows starter 691564.

https://www.bantasaw.com/catalog/viewpr ... ?i=&p=6680I've never actually worked on a vanguard twin but I'm guessing it's safe to assume someone in the past put the wrong starter on it. I will slip over tomorrow with a magnet to make sure flywheel on it is indeed steel.
Magnet may not tell you much as the flywheel itself may be cast iron and thus can attract magnet through the aluminum (or plastic) - the real way to tell would be take a little file and file off a few shavings from the bottom surface (make a little bevel on a tooth perhaps) of the ring gear and then see if magnet will pick up all those filings. If it don't then you have aluminum ring gear. More often I'd simply stick a little inspection mirror under flywheel and look for the tell-tale rivets or screws that were used to hold aluminum or composite ring gear to the flywheel ( I believe steel ring gears were only a heat/press fit - frozen flywheel and ring gear heated with torch to put it on , much like ring gears were put on automotive flywheels)
Steel ring gear was not that common and I doubt you'd find one on a lower end consumer model rider... matter of fact I can probably count on one hand the number of steel ring gears on Briggs engines I have dealt with.... so I never even stocked the starter gear for the steel gear flywheels.. and only ordered new gears perhaps 2 or 3 times in 20 years.
Finally you say the starter works fine with the used gear you put on it - in that case you don't have steel ring gear - gear tooth counts are different for the steel gear vs the plastic gear, so you'd have almost immediately noticed the difference soon as you cranked it over. (which is why they say not to use that gear on steel ring gear flywheels in the first place)
