I have a 79 4LF4 R2109. I had a problem with the car stalling over the summer here in France. Whipped out the plugs last week which were black( I had to keep putting on the choke to stop it stalling) and then cleaned them put them back and adjusted the idle speed. Car was running fine but then started to misfire and lose power for a 10 secs or so. Yesterday ran fine, today wouldn't hardly run at all this morning, misfiring, very ragged and shakey and even backfired (which is super loud in a 4L!) and bad again this afternoon then this evening all fine again. I did however notice that even when running fine the exhaust was pumping out black smoke and soot. Also fuel consumption has gone up. Looking initially at the misfiring, I took the cap off and the rotor looked worn. Was planning on replacing condenser, points, rotor and distributor cap but I'm told problems there might not necessarily account for black smoke. Reading on here could it be a carb problem? Or a combination of both? The 28IF carb was replaced earlier this year with a brand new one. Any guidance about either issue gladly received.
