Re: Carb Float Issues
you might have better luck checking with one of the engine sellers for a float epoxy will dislove in gas unless you can get some epoxy called safetypoxy used to build airplanes and their fuel tanks. The patch should be kept very small so it won't weigh down the float. I haven't had to mess with the float yet but if its the seam you might try superglue and use bakingsoda rubed into the seam or crack and put just a touch of superglue on the soda.
with fuel or fuel vapors inside the float you have a small bomb if hit with enough heat to set off the vapors.
