b61fred Posted August 1, 2005 Share Posted August 1, 2005 Hi, drove the old b61 around and put a trailer on it, The truck has a 673 N/A and the engine runs good but, not much power and hardly any smoke. I might have a injection problem. has anyone turned the pump up on these? I would like to try and see what happens. fred Quote 15 gears...no waiting!
