How are you priming it? They need exhaust pressure to pressurize the fuel tank. The pressure in the fuel tank then pushes the fuel to the carb. Put finger over the end of the exhaust when first starting, to build pressure in the tank. See the hose coming from the exhaust pipe to the tank. Also, that can get pinched,. or cut/worn and you wont presurize. it can take a bit, to get fuel into the engine.
