Hello,First POST. Took my boat out today and the engine died. Gas was leaking into the water. Pulled off the cover. On the passenger side of carburator there are two screws above the float bowl. The one on the right has a spring and I'm missing the one on the left were gas is pouring out. Does someone have a SCHEMATIC of the carb? What does this screw do, besides leak gas?Cap, Idle, Air,? A link for this screw? THANXS, any replys appreciated!-BEETS
