Hello; I'd look for a leaky fuel line, maybe inside the tank, or , perhaps the pressure tap is blocked. It could also be a partial plockage inside the carb. Open the throttle and blow on the pressure line and see if there's any fuel coming out of the main jet. If there is a blockage unscrew the main needle and blow until you get fuel out of where the main needle was. If your lucky the fuel that comes ouot will carry the obsrtuction with it and you'll be good to go. There's a few things for you to do.
