The Tecumseh 4 stroke engine on my (old) Ariens snow blower has
progressively required more choke to keep running.

Everybody might be right. Too much air OR not enough gas.
If the carb is loose, suspect the air problem, a relatively easy fix,
although getting a wrench on those bolts can be a knuckle buster. Don't
round the corners off the bolts, eh?
Second time tightening the bolts, I found that if I took a few minutes
extra, to remove the muffler, it was very easy to get at both bolts.
