I've checked almost everything and know I'm still learning about flathead engines and have a long way to go. I need you guys to again help me with some ideas as this is a brother type site and you have made me feel just like that by your past assistance. Thks John

It's normal for the car to buck in third gear at speeds below 20 mph, and for that reason it's best to downshift into second at around 25 mph.

Look down the carb throat and watch for fuel jets in both barrels as you work the throttle, If weak, or one side doesn't show a jet of fuel, the accelerator pump in the carb is not working, This can be from alcohol fuel attacking the pump, or the stroke adjusting link on the side of the carb being loose or not connected. If the car has backfired, the power valve diaphragm is likely damaged.
