Okay, it sounds like a float problem to me too... Look down the top of the carb. into the float to see anypresense of gas... Have someone crank the engine and watch the fuel to see if it does anything in the float.
If you want, you can pull the top off and check to see yor float is working right... I've got a pic. in my techie section you can look at to see if yours matches.
Check your fuel filters and fuel pump...
Is your choke opened all the way? Are you running the engine straight from cold-start? What happens when you hold the throttle higher than idle?
How does it run when it runs? All these questions should pin-point to one thing. The better you end up decribing your situation, the better we would be able to help!
