a cat buddy of mine brought me his sled,it would spit out fuel from the overflow hose on the pto side carb. I checked the needle and seat all is good there,running 330s for mains,and 1 turn out on the fuel air mixture screw.also if you let it idle for more than a minute or so it loads up bad enough to drop the idle and eventually kill it. leaned out the oil pump a little because there was a teaspoon of oil in each port when i took the y-pipe off,plugs look good. ANY IDEAS!!
