Glenn, after you get squared away with the leak here's food for thought.
Someone here, who said they were a small engine service tech, advised not shutting the valve off on a regular basis saying that they tend to fail if used very often.
Up to that point I had used mine once and haven't used it since, not even for the off season shut down (2 years.) I treat my gas and siphon out last years fuel at the beginning of the next season and re-fill with fresh, also treated, fuel.
I hope you get your issue resolved with little hassle..........
Go left.....No, your other left!
