I need to swap out the accelerator pump on my rear carb but I can seem to get the good one out of my junk carb set. I didn;t think there was anything securing them in there but I seem to be wrong. Looking up through the pump inlet in the bottom of the carb block there seems to be a phillips head cross in the bottom of the pump.. is it actually a screw.. it's not metal.

Nevermind.. they were just stuck and I pryed them out with a screwdriver. In the end it turned out to be a clogged prechamber for the fuel needle.
