I just got a 1972 honda cl350. Both carbs leak from the overflow
tubes. I finnaly discoverd a small hariline crack in the brass
overflow tube that is connected to the float bowl in each carb. Does
anyone know of anyway to path it? Also, has anyone else had this
happen before? Thanks.

Identical hairline cracks on an overflow tube in both carbs
sounds a little odd. Are you sure about that ?
My first bet would be that the floats and/or float valve need
replacement or at least an adjustment. Sounds more likely
than two matching hairline cracks.
If I had a problem with a crack, I'd probably attempt to coat
the cracked surface with an epoxy coating, being careful that
I didn't apply coating anywhere that would restrict gas flow.
I'd then shop for junk carbs on eBay to replace the cracked
casting.

I'm absolutly sure it's the cracks. The valves work perfectly and the
floats move freely. I was stumped untill i decided to take out the
floatbowls and fill them with gas just to see what happened. At about
halfway full, way before the overflow hole, they started leaking.
I was thinking about coating them somehow. Recomend any particaulr
epoxy? Thanks.

I'm a big fan of "Quick Steel", and "Quick Aluminum".
It is a stick of two layer putty that you cut off what you need and
work until it is one color before using. It is much stronger than the
old JB Weld.
JB Weld is now selling a version of the same thing.
Happy Trails!

I am a big fan of soldering brass but it may no be possible in this case.
