About a year ago I did a carb teardown, clean, and rebuild per Larry's guide. At the time the o-rings on the fuel cross tube had dry rotted and was leaking fuel. I was able to solve that problem but developed a new one. The left carb now has a steady drip from the overflow drain hose. I swapped several original and aftermarket floats and fuel needles, but my persistent fuel drip continues. I took a closer look tonight and I think I may have a split in the overflow tube near the base where the brass meets the aluminum. I'm hoping to get a second opinion before I follow the repair procedure in Larry's guide. Has anyone else made this repair? Any advice? Thanks!

I tried to solder mine but my soldering gun and skill lever are subpar so I just bought so brass tubing from the hardware, drilled out the old tube and glued a new one in with JB weld, worked like a charm.

Jb weld may work on the split as well. I plugged a couple of pin hole leaks in my son's gas tank over 2 years ago. still no leaks. One of their products specifies gas/oil resistant.
