My 53 3/4 ton is running ruff, think its carb problums. just re did the hole body and looks great in RED but runs ruff. How do you tell if the carb is at falt? It came with a cupple of old ones in the deal and how hard is it to rebuild them? Also how can you tell what type they are/ Its a 216 ci. and Its a honney. Thanks Paul
