I had the same problem with my '49 Farmall M. I ended up having to re-do the entire fuel system, as in a new line, sediment bowl, screens, and a carb rebuild. To do all that, it isn't that hard. What I would do first is shut the fuel off, take the sediment glass bowl off, and turn the fuel on to see if you have dirt at the bottom of the tank which would restrict fuel flow, or to see if your tubes inside the sediment bowl housing is full of rust, dirt, etc. If fuel is good there, put the bowl back on, but make sure to fill the glass bowl up first so an air pocket won't stop fuel flow. Take the fuel line off the carb, and turn the fuel on. If it doesn't run out there at a good pace, then it is not the carb. If is runs out good there, check to see if your float is rubbing on the top side of the carb. That would indicate that the float is stuck at the top of the carb, and not releasing the needle valve. But, I warn you, do not bend the float, or you will have bigger problems. I had to remove the carb off my M 23 times before I figured out that I had a bent float. Bent floates will make you not get enough fuel, or worse yet, make your carb overflow. Best of luck with it!!
