Default Re: Flathead Gas Mileage

Block off one carb between the carb and the manifold. You could be over carbed. The excess gas could be washing down your cylinder walls NOT GOOD. Any gas in your oil? Clutch slipping? Brakes dragging. Will the car roll easily pushing it on even ground. Ford said with the orginal system 15-20mph which I think this is far fetch but depends on your driving habits. Any time you modify, you change the characteristics of the economy of the car. Sometimes for the better and sometimes for the worse. More of my 2 cents, I wish I had more sence.. Gordon
