Which way around did you put the main jet back in, and is the hole in the center of it clear?
Did you separate the gasket from the diaphragm, and if you did, did you put it back together the right way - diaphragm against the fuel tank, then gasket on top, then carburetor on top of that?
Did you pump the primer three times, and was petrol squirting out into the throat of the carburetor?
