IIRC your probably gonna be stuck with utilizing the same type and model of carb already on that motor as supplied by Tecumseh, unless your able to manufacture an adpater plate and into tinkering.
What is the problem you have that you need a complete new carb? They can b rebuilt for under $20 or so, pretty straight forward and not difficult at all. I had one carb on an old HM80 that had a cracked casting and the cheapest I culd find a new carb for it was over $110 from a small engine dealer. I eventually found a scraped HM80 engine and utilized that engines carb and rebuilt it.
