If you think those guys are winning because they run APD carbs you are sadly mistaken. They win by carring 3or4 in the bank and win by driving the finish line. My son put Rustin Mayse out Saturday night by running dead on with a 2 and a .009 light. Maybe i should be bragging on our new Bolaws fuel system but we havnt had it long enough to brag yet Those guys can put your ass out with a junky Barry Grant carb.
