Does anybody know what the correct metering rods and jets are supposed to be in a '64 2X4 car on the rear carb? They do not match the '64 shop manual. Shop manual shows the following: Carb number: 3646S Primary Jet: 120-256 Secondary Jet: 120-222 Metering Rod: 16-219 The best I can tell, my carb has the following: Carb number: 3646S Primary Jet: 120-159 - different from shop manual Secondary Jet: could not identify Metering Rod: 16-440 - different from shop manual When I had it apart, the secondaries were smaller than the primaries, but I could not read the numbers.
