Re: Sooty, black plugs ???????
Good ideas from everyone....John's thought is often overlooked, been there myself.
An internal leak on Stromberg is usually the mechanically operated power valve.
Whether new or used these babies can leak. The leak occurs when the motor is running and producing vacuum drawing fuel from the acc pump well out thru the J tubes when not needed. Uncle Max is THEE guy however and let's get the real scoop from him.
