If the 194 is in a Chevy II and you are using the original pedal assembly and throttle arm, make sure you check the carb opening. On mine using a single Edelbrock with a cable connected to the original arm, the carb opened fully by moving the arm within the engine compartment, but when using the pedal there was enough slop, binding wear etc that the secondaries were not opening. Went to a Big Al's "hot rod" pedal and it worked great.
