I have the same starter kit for a 5hp Tecumseh but it does Not fit the older H50-H60 Tecumseh engines. I have an H50 on my old rototiller and a spare H60 engine in my shed. Both are off of old snow blowers and both have the starter ring gear. The mount on the newer starters is different than the older ones. It won't bolt up.
Heck I'll sell ya my old Snapper blower cheap. It's 24" with a 5hp Briggs engine. It does OK but you gota go really slow. Just not quite enough power to cut through drifts and that wet crap that the Plow trucks always push up into our short driveway.
I went to an auction the other day and ended up buying a 1998 Cub Cadet 1030 blower for $60. 10hp 30" cut. Hasn't run in 10+ years but I got it running pretty good with a quick carburetor cleaning. Need to clean it a little better and replace the fuel line and all 3 belts but I think I got a heck of a deal.

Not a bad looking blower. Do you have any Sears stores left? We have 1 small Sears store left. The big ones in our local Malls all closed up.
This craftsman blower is the same MTD built blower Minus the headlight. Almost $200 cheaper. https://www.sears.com/craftsman-24-in-208cc-dual-stage-snow-thrower/p-07188173000P?plpSellerId=Sears&prdNo=1&blockNo=1&blockType=G1
The Cub Cadet stuff tends to be a Little better built. Look at the sides of the blower. The cub has several stiffening bends stamped into it. But they use the same transmission, Auger gear box and engine. Don't know if there worth the extra almost $200 more than the Craftsman though. Both will be easy to buy parts for if you need belts or what not.
