Re: 1938 Packard Six smoke and strong smell of gas coming from exhaust

Doubt you have liquid gasoline coming out of the tailpipe. Gasoline is a hydrocarbon so the liquid your seeing drip out of the tailpipe is condensate water formed as a byproduct of the combustion process. A little white smoke at startup is normal, but a lot is not. 1. Pull a spark plug and see the color. If it is dry, black and sooty, the carb is too rich. Adjust the mixture valve on the carb to a leaner state. Oily and black would indicate piston ring problems. Plugs should be a tan/grayish color. 2. If plugs look fine and you're blowing lots of white smoke (think mosquito fumigator) then you likely have a headgasket issue where coolant is entering the combustion chamber as Mr. Dyneto indicates.
