Last summer I put kits in 3 carbs (2N 9N and 8N) and changed 2 of the floats for new ones. One original was bad and I put the other float on the shelf as a needle and seat did the trick. This spring all 3, the 2 new ones and the one old one failed after about a week. They are all leaking on the top seams and I was thinking I should just resolder them all. what are they like to do? The top seam leaks interesting because the float won't fill up right away until you drive it and it shakes around a bit, so you think it's fixed then you don't get far before it is leaking on the ground.

I've repaired brass ones for cars but the brass seemed thicker. anyone else have these mass failures on floats or repaired them?
 
Glenn,Yes I have noticed that after market MIC floats have poorly soldered tank joints and some have had leaks.I have re soldered some of the leaking ones.You just need a good liquid flux like Ruby Fluid Liquid Flux and a small acid brush to clean the brass and make the solder flow out thin for a good repair.Don't pile the solder on because it is heavy and weights the float down.Once soldered they can be checked for leaks in a pan of hot almost boiling water,drop the float in and sink it with a fork ect.and watch for bubbles.
