This guy has some good videos on small engines...
My Craftsman with a Tecumseh engine was running as the OP stated, it needed the choke on to run smoothly. Mine had to be on the 1st click, where 0 clicks is off, and 3 clicks is full choke. If I turned the choke off, the machine would stall out.
I have one of these non-adjustable carbs, and followed that video. Turn off the gas line, run the machine dry, then unscrew that bolt and clean the holes with a piece of wire. Should help a little, it did for me. The jet was a little dirty for whatever reason (stagnant fuel, dirt in jerry can, etc...)
I may be completely out to lunch, but please, no torching.

I just bought a Craftsman snowblower model 247.889720 with the 208 cc "quie
t" motor. I had a similar problem--uneven running with the choke supposedl
y open. I found that the dial for the choke has confusing markings. Straigh
t up and down is usually a full open choke. In this case, a full right tur
n is a closed choke, up and down is half choke, and all the way to the left
is the open-choke, running position. Very unusual. At first, from the mar
kings, I thought left and right turns closed the choke. It was functioning
but not running smoothly in the up and down position, could smell lots of u
nburned gas and the fuel consumption seemed very high. On this model there
appears to be no air filter and it would take a lot of disassembly to actu
ally see the choke blade in the carburetor. I decided to experiment with t
he full left position and that cured the problem--smooth running and no sme
ll of unburned gas from an over-rich mix due to the choke being half closed
