1998 grizzly 600 is leaking gas out of the bottom of the carb where a gas line attaches. Schematic shows an overflow line and a brether line. Each line connects to the bottom side of the carb and discharges under the atv. One line on the left side and one line on the right side of carb. The right side line leaks gas out the end of the line when the gas valve is turned on and while running the motor. Not a little drip. This is a constant stream. Why is my carb doing this? Float problem? Thanks in advance!
