I have what I believe is a 1956 235 with hydrolic lifters in my 1953 Chevy 3100.

I have disassembled the carberator and replaced the acellerator pump. The origional one had a broken arm that pushed down the spring and the pump. "it looked like a kit of some kind and was not the origional arm" I got a origional piece from jim Clark classic truck parts and rebuilt the carberator.

When you run the pump with the top off gas squirts up from the spring loaded check valve next to the pump and it seems to work normaly. When you put it back together and run the pump no gas gets squirted into the carberator venturi. When you put your finger over the spring loaded check valve part and run the pump you have to be careful because you may squirt yourself in the eye. "Yes I did that... ouch"

My question is... where does the gas squirt out when it is assembled? I must have a blockage of some sort. I have the service manual but it does not have much detail. I keep looking at the top section of the carberator "the part above the spring loaded check valve" and it is solid. There is no where for the gas to go.

When you push down the gas the engine stalls and then catches up. I know my problem is because no gas is getting squirted out but I can't figure it out.
