leaky carbs



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