#3 carb float cracked at bend. <br /><br />float of course filled with fuel from the bowl and no longer was a float causing engine to flood.<br /><br />was able to drill out the plug, drain the fuel and allow it to dry. used soldering iron and rosin core solder (it sticks!) to seal crack & refill plug.<br />held under water for 2 hours without any bubbles/leaks from any joints.<br /><br />main question is what caused the cracks in the first place? pressure difference? i can't imagine the float is stressed much inside the bowl.
