How long should it take for it to run out off gas when you turn the valve to off? Reason for asking is that when i went riding the other day, I rode 8 miles and my 4 wheeler started cutting out like it was out off gas... Then i remembered to turn the gas back on, Turned the gas on and it was like it was supposed to be. So when i got home, I turned it back off and rode around the house and stuff, never one ran out of gas. I didn't think it took long to run off when you cut the valve off? What do ya'll think?
