I too have a Snapper 21" High VAC ( 2008), self propelled, on which I ruined the engine...yes I let it get really low on oil...never done that in my life.
I held onto it as it s steel framed unit in outer wise excellent condition.... and they do such a good job of vacuuming.
Its a 675 Series B&S, 190 cc.The mower is a P2167519B, Part no.7800175,Ser#20000744241.
What has kept me from ordering a new engine is the dazzling array of 675 series engines.....
shaft size, keyway size that I found when I looked into it. I can do disassemble and reinstall but I'm not
much of an engineer if its the wrong engine for the Model.
Its up at my farm and I will take a much closer look at the engine this weekend. I'll get all the info I can find on the
engine plate.. all that.
Any advice on where to look as well as order.
I'm new to the site and forum. Appreciate the advice.
