Here lately i just replace 2 cycle carbs once they're confirmed they are the issue. The diaphragm should be very pliable, if it's stiff, its bad.
according to Sears parts direct the carb PN is 753-05633, like you said.

New are around $40 from the maker.

it doesn't appear MTD sells a repair kit... If i can find out who made the carb (Walbro, Ruixing, KeHin, Zama) a rebuild kit could be found.

Unless you used the really expensive Walbro carb cleaner o spray out your carb with, you have just destroyed it
Automotive carb cleaner destroys the seals in most check valves used in cube carbs
Despite what the experts on You tube say, if you pulled the carb apart then the gaskets need to be replaced because 90% of the time they will not be able to make a pressure tight seal again .
You can soften then by cooking them in warm oil , boiling in water or a variety of other bodges but they will dry out again and leak again.
That is why the wholesalers sell common gaskets in 10 & 20 packs

really can't make any guarantee's on the aftermarket carbs. If it works proper, and you save money, good deal.

my policy is always Use OEM parts with 2 exceptions, The customer cant afford it, or the original part is no longer made.

generally the manufacturers name is stamped into the carburetor, location of it typically varies by carburetor.
Someone with more experience like Ilengine, Rivets or startech might know just by looking at it,
