I have put a 79 stock carb on a 82 motor and i try to start it and once i get the engine running(not running under 2500 rps, wont idle) and then turn it off the carb will empty out the bowls, i figuared somehting was wrong with the carb so i then fixed my other 82 carb and put that on the motor, the motor was already sorta flooded fromt the first carb and then i tried firing it with the 82 and it did the same thing, puked about half the bowl of gas into the carb to flood it more, what have i hooked up wrong, is it just 2 sour carbs, please help

 

What kinda fuel pump? Stock? Either too much pressure, or sticky needle valves from sitting with old gas in it. tap the banjo bolts to try and get the needles to seat.

 

everything i beleive is stock we bought a new fuel filter, we did take the top half of the carb off and cleaned the bowls out with rad and air pressure, how can you tell if the valves are sticky? and if the banjo bolt is the bolt in the middle of the carb we taped it, we taped it alright haha. could it be a float bowl vent solenoid that needs to be hooked up, i have no idea where that is but that was also sugested, thanks

 

o yah i forgot to mention, both carb were for the motor with no gas in it for about let me think, the 82 about 6 months and the 79 about 4 month, the 79 didnt do this puking b4, it was put back on but about after 20 times of starting up the car and turning it off it started to do this

 

the carbs were off* spelling error

 

any other thoughts?
