I recently discovered gas dripping from the "handle" of the petcock.  I had recently disassembled and cleaned said petcock.  I rode the bike with no problems then 2 days later, drip.  I moved the bike outside and the drip seemed to stop.  Now I can't find any drips but there is a strong odor of gas.   I can't find any anywhere but if you leave the bike in the garage overnight it is overwhelming.  Also, I just filled the tank when I rode last Thursday.  Any input or ideas.  Where is it coming from?

when you put it back on use a open ended spanner  a screwdriver doesn't do the bolts tight enough.
