ive got a holley 2210 2bbl on a 318 in my fifth avenue. i had it on before and when i would hit the throttle it would cut out and if it was under load like at a red light it would stall. i rebuilt the carb and it still cuts out but doesnt stall out like before. the accelerator pump is adjustable and i was wondering if i should adjust it for more fuel or if its something else?
