Wellllllll I got the flathead 6 fired! A night of soaking rings in Liquid Wrench, then tossing a boat gas tank to the fuel pump with new fuel and a carb from a 53 Chevy. Ran for about half an hour. Smoke almost went away, it runs not bad. Compression went from 25-90 to 85-125 worst cylinder to best. Engine might be ok! Truck has 59,000 original miles......
