Have you set the carb up correctly and made sure there are no blockages ?

Have you left it long enough to warm up?. ( its a heated carb and runs alot better when warm)

I have an idea but want to be sure you have checked the basics first.

You need to make sure all the jets are clean.

There is also a power jet that is cast into the float bowl ( the small pipe that connects the float bowl to the main carb body). Try and blow into it and make sure its clear.
