Sorry model is 350447 1118 E1 flywheel # is correct 808768. If you still have it I will take it.
I checked those 2 B&S engines we have for parts, they are NOT a Vanguard engines, they are 27 hp Commercial Turf. So I looked up that Engine and they make 4 different flywheels for that model #, 3 are NO longer available and the # you gave is one of them. 1 is available still but it's # 844819 and is for a recoil / rewind start engine. If you could find someone that had that 844819 flywheel, compare it in person and....if, BIG IF, the only difference is timing keyway, you can still use it.....I can tell you how! Good Luck!
