These are the two closest numbers I've came up with... either way looks to be a 7hp?
143.646032 H70-130183A
143.646062 H70-130013B
or maybe not...
HM80-155038A,HM80-155038A, 155038A-HM80, 143-646052 Craftsman
Also I pulled the recoil cover and this engine doesn't have a coiled mounted outside the flywheel... not sure how different that is than my HM80
