In the spring of this year I had to clean out old gas from the bike sitting for a couple of years. There was also gum in the carb, and I cleaned the petcock and tank as well. Got the bike running great.

It sat in my garage for a few months, and I went to start it, and it won't start. I squirt a bit of gas in the carb, and it runs, and dies. So I know it's a fuel problem.

I disconnected the fuel line, and no gas comes out. The tank is full of fresh gas. umm..

Anyone have any idea's of would the problem is?

 

Does this have a vaccum petcock??

Yes, it does. I've applied vaccum to the petcock, and gas flows fine. The vaccum line splits to carb and another electronic gadget. I have no idea what it is, but its mounted under the tank next to the carb.
Here's a pic:

Could this be the problem?
