I have a 15 HP gamefisher motor that is a 1989. I just got my tank and fuel line all together and took it out to test. I had a hard time starting it, and there was gas all over the water and i hadnt even primed it yet. once i got it started, it wouldnt idle all the way down, and when i was cruising around the lake, it was acting like it couldnt get enough gas because it seemed like it was running out. I think it may be getting to much/to little gas, but how would i go about adjusting that on the carb? Thanks alot
