the stumble could be a lean or rich stumble. Besides the squirters, you have a selection of accelerator pump cams that can be used with different ramp rates. Sometimes the bowl bleeds need to be opened up slightly. I cured a lean stumble by going to a 50cc pump shot and a slower ramp on the pump cam and a slightly larger squirter in my last car.

Jason Fletcher's carb web site has a lot of good info in it - check that out too.
