I've read your posts and I get more confused everytime. Can you please type the whole word. Anyway I'm not sure what you mean by rumble and where does that happen at....idle, cruise or taking off?
The squirter in the carb is to help stop the car from stalling because of the low vacuum signal when the throttle blades open up. It gives the motor enough fuel to run before the vacuum(not engine vacuum) starts to pull fuel from the boosters. If they are plugged it will stall the motor when you mash the gas.
If the plug wires are bad or oil soaked then it's time to replace it. What motor are you messing with?
