Engine running rich through one exhaust pipe?
« on: April 23, 2019, 12:37:11 PM »
My 440 has dual exhaust and a Fitech throttle body and a fresh HP Digital Petronix ignition box has been running rich on the Driver side.  That same side is leaving a sooty black  stain on the floor. The engine idle has been a little rough especially in the morning. I replaced the spark plugs 2 months ago (all the old plugs looked about the same) along with a fresh MSD rotor and cap. Any ideas? I am guessing the ignition system. Could my MSD distributor be the problem?  Where do I start?
