The Ford Barn - View Single Post - White tailpipe exhause briefly after starting

fordfun · 06-21-2016, 10:35 AM

Shortly after start-up there's a great deal of white exhaust smoke coming thru the tailpipe on my 1929 Sport Coupe with Mod. B head & carb. It clears in 2-3 minutes, and is not present while driving. I start the engine with the GAV open 1/2 turn, and close that as soon as the engine runs without stalling (by closing it too early). Closing the GAV seems to have no immediate effect on the smoking. It seems that the longer the car sits between drives, the longer it takes for the smoke to clear. Any thoughts on what's going on here?

Thanks - Bill
