you have gotten all great answers ! and you need to do it all and also do it twice ( like blow out the gas lines both ways. and especially the curved line going into the carbuator into that filter ! but! after doing all of that ! I went to the neighborhood auto parts store and bought me one of those cheap --inline--electric fuel pumps --$30 + back then -- and never again did I have a problem -- TURN ON KEY ! CLICK CLICK CLICK OF THE PUMP ! AND STARTED RIGHT UP ! ENJOY YOUR CADDIE ! I MISS MINE ! IF YOU KNOW OF ANYONE NEEDING A 429 ENGINE ? MINE HAS 83,000 MILES ( NOT RUNNING --JUST SITTING NEXT TO THE BARN ) FOR THE ENGINE AND TRANSMISSION TOGETHER $500.00 , WELL , GOOD LUCK !! Mike in FLorida

I had this issue as well. The fuel line was clogged. Disconnect the lines front and back and blow air back towards the tank. It should flow freely. If it does not this is your issue. If it does check your carb to see if it has a brass filter at the carb It will be a large nut thast the fuel inlet screws into remove that and the brass filter is behind it. If that is not it you may have a stuck float needle in the carb. Remove the top of the carb and free the needle. Hope this helps. Cheers,
