Yet another question concerning my first bike, a 76 Honda 360. I found a petcock for it on a '75 350, and I spent a few hours getting all the gunk out of the sucker. When I reassembled it and put it on the 360, it leaked like a sieve.
It looked like it was mostly leaking from around the area of the on/off/reserve switch, so I took it back apart. It turns out one of the gaskets in there is completely shot. Not the black rubber gasket with 3 small holes in it, but the metal gasket that goes around the edge. I knew it was all bent up before, but I thought it may lay down flat when I screwed the switch back on.
What I'm trying to figure out, is if I need to buy a complete petcock rebuild kit just to replace this one gasket. Or, maybe can I just get a rubber O-ring of the same diameter and use it instead (and if so where do you think I could find one). Thanks you guys for the help before, have a good one.

*my topic is messed up...meant to say "spend $25 on a petcock rebuild kit." The petcock alone sells for about $50, since they don't make em anymore.

The round gasket with the holes is doing the leaking.
Look at the lever where it touches the round gasket. it has to be perfectly flat, with no ware marks, or it will leak.
If you want to try, carve a new round gasket out of a big piece of rubber.
Or don't waste your time, get another petcock. Most of the time, complete petcocks are changed. People rarely bother rebuilding them, so the rebuild parts might be available.

The rubber piece with the holes in it is what is leaking. The metal gasket you talk about is not a gasket, it is actually a spring meant to keep the lever assembly tight against the black rubber piece. Don't hammer it flat. Rebuild the thing, leaking gas at some point is going to cause you a big problem. It will be money well spent.

Don't worry about the petcock shutoff as long as it dosen't leak, and won't shut off. Go to a plumbing supply store and get a small brass shutoff that will fit in the gas line and two small clamps. cut line where you can get to it easy and insert shutoff. Had the same problem on a Honda 1975 Cl-360, just remember to shut it off when your done rideing and turn it on when you start up.

yu would probably be better off replacing the seal but you might try using some fuel rated form-a- gasket for a temp fix. Good luck.

Just make a gasket for it. Either cut one from a car carb gasket or make one from liquid gasket compound.

NAPA should be able to get you a Fuel rated o-ring. But I would just buy new Its your first bike, do it right if you can.
