A picture is worth a thousand words.

That being said, is the block a single casting or does the cylinder bolt on to the crank case? Is the magneto base mounted or flange mounted? Is the spark plug verticle or at a 45-degree angle? Does the exhaust screw into the block at an angle or is it perpendicular to the crank shaft, or does it screw into the intake manifold? Is it a side draft carb or an up draft carb, what brand, and what L-number is on it? What is the Y-number is on the magneto? How many head bolts?

I suggest you Google "Wisconsin engine" combined with the following model numbers, that will tell you what family it is in: AHH, AEH, ABN, BKN, AENL, S-12. Or go to the Wisconsin Llc web site and browse the parts diagrams.

Well according to the Aa-91-A stamped on the sump it spears to be an aenl. Block and sump are one exhaust threads into block on an angle. Spark plug is straight out of head. And spears to be an up draft style carb. With air cleaner mounted up like a stack

Yep. That sounds like an AENL (or the less common AEN which is very similar). The whole manual (not just the parts list) is on the Wisconsin LLC web site. Common engine, lots of parts available. Good working engine too.
