Take the gas line off at the carb then turn on the gas, you should get a good stream of gas, not a dribble.

Get rid of the in line filter. The sediment bowl is what is supposed to catch the heavy stuff. A screen in the carb catches the rest.

The vent in the gas cap is a probable excuse. When you have the gas line off the carb and let a quart run thru it, if it starts to ween off, open the gas cap. Restored flow indicates a blocked vent.

What you may have is scale in the tank that covers the inlet of the fuel bowl fitting in the bottom of the tank. Scale is a problem in old tanks. Remove the bowl from the tank and see if any junk has settled in the fitting. If it has, clean & dry, then vacuum the tank as best as you can. After that, find a 3" piece of copper tubing that will fit inside of the fuel bowl tank fitting and solder/press it in. Crimp the top shut and drill a couple dozen 1/16" holes in the copper tube stand-pipe. Sediment will settle to the bottom of the tank, but gas can still be pre-filtered thru the stand pipe and not clog the bowl's fitting. Has cured several tractors I've had.
