Petcock Lines Drip Drip Drip

66 CL77 running ok recently till I ran out of gas (pushing no fun), so got home & 1st time that I put in a decent amount of fuel like a gallon (had been hesitant since just put on newly painted tank w/crossover under frame & wanting to insure nothing leaked). Therefore just small amounts put in like a quart.
Smelled gas one morning in garage, sure enough I just touched the fuel overflow tubes with my finger, and I see liquid on my skin. I had shut off fuel flow after riding,to the off position.
Question though--right side petcock outlet still drips a drop of fuel like every 5 seconds, left side about every 30 seconds. Tank is basically "empty", must be some residual fuel left in there though. I get the drips whether in off, on, or reserve on the petcock. So does the dripping cause the bowls to overfill when bike is sitting overnight? If so, is the problem at the petcock?
Before I pull the carbs again to double-check floats & gaskets, I'd like any input on above. The tank has been cleaned, de-rusted, lined also. Installed petcock rebuild kit last winter, but sure am wondering why the line does not "shut off all the way". Thanks.

Try removing the fuel lines from the petcock to check if its the petcock itself that is leaking.

I had done just that to observe the drip, drip. So perhaps a new or used/reconditioned petcock is in order? What do you think? Thanks again.

You may need a new packing gasket

You should also check the fuel lever face for pitting and flatness. I dress mine on a pane of glass with fine sandpaper.

How hard is it to turn your petcock lever? If it turns really easy it might need a bit of spring tweaking so it seals better.

That is a good point, but mine is quite firm so I think the spring behind it is good. I did clean the face as Hoosier suggested, there was some pitting on the back. Am ordering a new fuel strainer just cause this newest one I put in looks like a tad blocked already. Kind of gummy looking.

I will ditch the crossover fuel tube--what's a good way to block off those 2 outlets? I don't want to use bolts in a cut-off fuel line, would rather find some type of gas-resistant rubber nipple of some sort. Ideas?

How about checking to see if the two fiber washer/seals that go on the two screws that hold the petcock to the tank are there. I've seen a few parts catolouges that don't show them and if they are missing or rotten the fuel will leak past the screws and bypass the shutoff valve.
