I hold my Ryobi 4 cycle gas weedeater upside down when doing edging.
 Oil leaks.
 I'm wondering if it's possible for oil to leak out of the air intake valve
 (I forget the term: It's right behind the foam air filter, and it let's
 air into the engine or something) I thought oil from the gasket might go 
 into the piston and out this area.)
 Checklist please.
