Tried replacing the two small "o" rings on the valve and it didn't work. Found a used one at local shop, screwed it on and all is well. This problem caused a strong gas smell from engine compartment and was easy to see after removing the air filter assembly. These valves are on E-bay for $25 to $50. I was lucky and found mine at local shop. Worth the risk compared to the $250 price new (excluding labor). Overall an easy repair even for a non-mechanic like myself. Oh yeah, a small spray of gas is emitted when the screws are backed out, so watch your eyes.
