you definetly need to give us more info on this subject but let me take a stab at it.
do you get gas squirting into the carb when you push the throttle ?
do you have any spark at a pulled plug wire ?
when your engine doesnt start it can be caused by any of about 5 different things.
but the first 2 things are spark at plugs and fuel in carb bowl.
i would rather push my Ford than drive your Chevy !
