once again i agree with grumpy about the fuel pump. i assume the pump is one that relies on crankcase suction to form a vacuumed which opens and closes a rubber diaphragm to pump fuel through. these particular pumps are very susceptible to tearing the diaphragm and therefore restricting the vacuum and not letting the diaphragm pump.
if the fuel tank could be mounted higher than the carby then the whole pump wouldn�t be needed at all and you could do away with all the crap. if you can get a replacement pump off the bloke you got the generator for free then try that. if all else fails then you could replace the pump with a Briggs and Stratton crankcase vacuum pump which i have found very reliable in the past. this is the type of pump i explained before. this all relies on weather or not you have the option of using crankcase vacuum which i think you do
