grndlprm Nov 15th, 08, 1:17 AM My 350 small block is running pretty rich and when idling I get quite a bit of white smoke from the exhaust. I've adjusted the carb, but that only helped a little. Looking for some suggestions on what else to do since the engine is running fine otherwise. Thanks in advance.

Pete seabees72ss Nov 15th, 08, 3:29 AM Heavy white steamy smoke? Running rich is usually a black smoke. White Steamy smoke, water in the cylinders Blueish looking, maybe considered white is oil. M.Maner Nov 15th, 08, 7:40 AM Spencer,if you drive the car for 20-30 min. and stop, does the car continue to smoke? Mike grndlprm Nov 19th, 08, 1:03 AM More details as suggested by Pete: Edelbrock double barrel carb with a working choke. The smoke is usually pretty light in color and continues even after running for 20-30 minutes. I usually don't see any smoke while driving, but I definitely see it when stopped and idling. Heavy gasoline smell to the smoke as well, which is why my first thought was that it's running rich. A. G.

Is there a catalytic converter involved? Not sure what an afterburner does to throw the colors off. If it is steam due to a blown head gasket, crack or such, you should be able to notice a drop in radiator water level. (DO NOT pull the cap on a hot engine -- I know everyone knows that, but I can't help repeating it). Most radiator shops etc. have a little tester that is supposed to pick up on any combustion products in the cooling system. Edelbrock 2BBL is news to me...?? seabees72ss Nov 19th, 08, 7:09 PM If it smells heavy of gas, its way to rich. Could be float level, Carb size, Jets, metering rods. Make sure your plugs, wires and timing are correct too. | ||
