Back in the day, if an owner of a Studebaker Avanti (equipped with an R1 engine) wanted good fuel economy, he would NEVER install 120-159 primary jets and 16-241 metering rods into his Carter Carburetor.....True?

True, because that would enrichen the fuel mixture?

Good thought.....however, not correct:(..........The jet/rod combo described above is thought to give very good fuel economy in Avanti R1 engines equipped with their original Carter AFB carbs! (EXAMPLE...Carb # 3589S).....ANSWER....False.

"thought" by who, Ed?

The (then) Carter Carburetor Company of St. Louis, Missouri.....whom  apparently used that combo as original equipment in their Studebaker 'economy' 3540S AFB carb.

(Not sure if they were considered first or second step 'lean' when installed in a, for example, 3589S carb)

(And, to be clear, 'lean' meaning capable of passing less fuel than jets and rods termed 'rich')
