Rochester carby problem

[johnneyblacksmith]

Hi all, I just pulled the top off my Quadrajet Rochester to clean the fuel bowl. It seems to pump fuel when the push the plunger but when you replace the top it won't pump fuel. Any ideas? It worked fine previously just the float would get stuck sumtimes.

firstly, why clean the fuel bowl? ....isn't there a fuel filter in line somewhere? (externally or in the carb inlet fitting?)
and also
don't get the comment ' seems to pump fuel when the push the plunger but when you replace the top it won't pump

You have to replace the accelerator pump plunger in its bore BEFORE you put the gasket on and replace the top airhorn cover
and have a FULL fuel bowl too!
