I've used the choke to limp the 125 closer to the garage myself when I've run out of fuel. I usually only get about 10 feet closer though. Many years ago my #2 125 would run fine for about 30 minutes or so then would spit and sputter then stall. Choking it would help for a short while. After it sat and cooled down for 10 or 15 minutes it would start again and run for about 15 minutes then do it again. It ended up being the condenser. Sooo choking helping does not always indicate a fuel issue. Just saying...
