Petcock is leaking past the vacuum diaphragm. This is draining through
the vacuum hose hooking it up to the intake manifold assembly and then
into the airbox. This will happen continuously, and over time, you'll
have a puddle.
Replace your petcock. Rebuild kits are available, but I swapped mine
and no problems since.
