Answer
HI GARY, IF YOU TAKE THE TOP HALF OF THE CARB OFF [AIR HORN] AND YOU MANUALLY PUSH UP AND DOWN ON THE ACCELERATOR PUMP WITH THE FLOAT BOWL FILLED WITH FUEL IT SHOULD SQUIRT FUEL OUT THE TOP OF THE VENTURIES. IT WILL NOT BE PERFECT, BUT YOU SHOULD FEEL IT AND SEE IT START TO SPRAY. IF NOT SOMETHING IS STILL PLUGGED OR THIS IS THE WRONG SIZE PUMP. IS THE PUMP LOOSE INSIDE THE WALL IN WHICH IT GOES UP AND DOWN ?? NO FRICTION LIKE ?? THESE AFTER MARKETS KITS ARE A 50-50 SHOT. WAS THERE A CK BALL IN THE BOTTOM OF THE PUMP HOUSING ??? SOME DO SOME DON'T. LOOK DOWN INSIDE AND SEE IF THERE IS A LITTLE RECESS..IF THERE IS THERE SHOULD BE A CK BALL..IF YOU ARE GETTING FUEL LIKE THIS BY MANUALLY PUMPING THE PUMP THEN I SUSPECT THE AIR HORN GASKET IS INCORRECT BLOCKING THE HOLES FOR THE VENTURIES..DID YOU MATCH UP THE GASKETS REAL CAREFUL..LET ME KNOW WHAT HAPPENS WITH THIS..GOOD LUCK TO YOU,,,TOM.
