I have a 93 wheel horse 314-8 and i had it running a while back but i noticed it was running rich. I started playing with the adjustment screws on the carb but it still ran the same so i then removed it and cleaned it out and put it back on. After putting on the carburetor i started it up and it ran fine for a few minutes but it started running rich again to the point when the engine was at full throttle it put putted as if it was idling and then i noticed fuel pouring out of the front of the fuel filter i removed the carburetor and broke it down and checked all kinds of diagrams and everything seems to be in order but i put it back on again and it does the same thing runs good for a bit and then pours out fuel.
