I need some help identifying this Wisconsin engine. The engine tins are missing, so It has no ID tag.

so the questions are:

What model is it?

what year was it built?

What equipment was it built for? 


Engine bore is 2-1/2" and stroke is 2-3/4"

AA91K-21 is stamped on the block above the oil fill tube in the gas tank support mount area

Underside of cylinder head is stamped AB 70L and (6E or CE or GE the first letter is hard to read)

The WICO magneto ID plat reads 1295   559664

he round ID tag on the zenith carb - outer circle L51B, Inner circle S1151 (I've heard this outer circle info on the zenith card is coded to what it was built for?)



 if anyone has some engine tins that fit it that they would part with, I'm interested.
