Rochester Carb Numbers

*1966:

4MV carb, 425 cid.

#7026250, Orange Coloured Tag, regular type #7036250, White Coloured Tag, with option K-19 (K-19 translates as "Air Injection Reactor System (Calif. Cars) U.S. Prod.")

---

**1967:

3 carbs listed for 1967 Toros:

7027131 : No A.I.R., No Climatic Combustion Control, Assembly code RN, ID Tag Colour: Purple, Primary Rod: 0.044", Secondary Rod: AU(?), Metering Jet: 0.071"

7027130: A.I.R., Either C.C.C. or not, Assembly Code: RM, ID Tag Colour: Dark Blue, Primary Rod: 0.045", Secondary Rod: AU(?), Metering Jet: 0.071"

7027132: No A.I.R., Climatic Combustion Control, Assembly Code: RP, ID Tag Colour: Gold, Primary Rod: 0.045, Secondary Rod: AU(?), metering jet: 0.071"

So 3 were available with 7027130 being the Californian one. 7027131 has C.C.C. and 7027132 doesn't. As far as I can tell, C.C.C. is their term for the exhaust-manifold-shroud-heated air cleaner set-up. It is option K-50.

Unfortunately, there are no service carbs available from GM anymore for the 1st gen.

Here are the numbers I get from the manual for the 1st and 2nd gen. Toros:

1966: This is really a wierd one, since the 425 only has listings for the manual trans and the Jetaway. There is no separate Toronado listing, as in later years. Here's what they give:

400&425 standard: 7026250 (w/o A.I.R.)

7036250 (A.I.R.)

400 Jetaway: 7026256 (w/o A.I.R.)

1966 Service Carburetors (a separate page, dated from 1972. You'll note the carbs have 1971 numbers on them):

400&425 Standard: 7041312

400&425 Jetaway: 7041310

1967:
