O.k, well that answers my question about the fuel petcock then. You have the older style one apposed to the newer type i have, the one i mentioned in my previous post with the On, Pri, & Res, setting is the one i am familiar with. They seem to be slightly different in design but operate almost on the same principal.
I would still speculate that the carb is the issue and would double check it again just to make sure. As for a blockage in the line it doesn't seem likely seeing you have fuel coming out of it when you pull it off at the carb. So i would check the carb again just to make sure, plus it's always better to start with the simplest and more inexpensive solutions first then move on to the bigger ones.
