94 octane stall

You probably got a slug of water with the gas. It's in the carb now, so you'll have to dump it out. Dump it into a clean dry bowl. Then transfer it into a tall small-base drinking glass. Give it a little swirl then set it down and watch the water gather itself together in the bottom of the glass, Simply fascinating.
If the gas is clear; not red, not orange, not yellow, then it is fresh enough to use,IMO and I wouldn't suck it out. But I would be prepared for more water to come up the pipe.
Isopropyl alcohol will bond to the water, and make the molecules small enough to pass thru the main jets. Yeah you will feel it when it does this. And it will still stall at idle cuz the low-speed system goes really lean, too lean to support combustion. When you feel it stumble just slap the gas pedal a couple of times, until it moves on thru.
