Hi everyone I'm a newbe I joined the group 5or 6 yrs ago but have been without a boat for awhile , I just purchased a1980 Crusader with a big block Chevy it has a high rise tunnel ram with 2 holly 750 double pumper . My question is the carbs were just rebuilt and the motor runs good but has a slight miss here and there I think the carbs need to be dialed at this point . Does the boat need to be in the water under a load to do this? And does anyone know someone that can fine these for me in or out of the water , I live in the inland empire area (Banning) thanks for any help and advise , Gary
