So took gas tank off. Petcock valve to off. When I go to ON barely any gas trickles out. When I go to reserve nice and free flowing. I changed the petcock valve with this one -> http://classiccycledepot.com/index.php?productID=145

because I broke the nipple on the older one. Why would it be free flowing on reserve. There is gas in the tank. Haven't driven it that much since the last fill up (premium gas). I'm confused. I guess I'll try it on reserve the whole time....
