petcock problems please help me

I have a 78 kz650 b2 that is complete and running but my petcock isn't working. When I originally took this bike apart I tried to drain the tank and noticed that no gas was coming out( I had it set to prime and previously the bike had not been running). So I am trying to find a petcock or a rebuild kit for the kz 650 and I've had no luck with the dealers or the recyclers in my area.

Thanks

Sounds like something that Jeff Saunders at Z1 Enterprises might have.
