Hi,

I just bought a 66 Toronado project that runs and drives. I'd like to learn where to locate diagrams and photos of other 66 Toronados with replaced Rochester carbs. It's my understanding that the original carbs were recalled due to fire hazards. I found an old, possibly the original Rochester Qjet with a plunger instead of needle and seat. The carb does not have it's birth certificate. Is there a source to get a copy of a build sheet or other docs to answer learn more about this car?

 

A 1966 factory Chassis Service Manual will have the original carb #s, or you can post them here and we can decode them. Look at left rear corner of the carb and you'll see a series of numbers like 702____. You should have that manual anyway- invaluable resource for working on your old machinery.


We can ID your service carb using those numbers too if it's a Rochester QuadraJet. Carter and later Holley also made Q-Jets for 60s cars with side inlet fuel fitting as your 66 would have had originally.


The original 66 Q-Jets had a weird float and valve arrangement as you've discovered. I don't think it was so much fire hazard as it was just a clumsy design. Later OEM carb kits had parts to convert the diaphragm seat to a needle and seat configuration.

 

Welcome to the site and congrats on your new project. A CSM can possibly be found through one of the guys on here or Ebay.

 

The only numbers I can locate on the carb body I believe are casting numbers shaped in a circle 7032720. Other items on the body have their own numbers. I'll check into a chassis manual, thanks for that info. A Rochester specialist is telling me that without the bottle cap ID# rebuilding and setting up the carb will get quite expensive. He also stated that I can't buy a rebuild kit for it and that they're to complex to setup for a novice.

I can however possibly rebuild the Qjet that's on it now and running poorly. Will the chassis manual display diagrams showing all options for linkage? I have cruise.

Thanks for your time.

There are many Toronado forums that can help also. Here is one example. You can search for others
.

 

Are these manuals originals or reprints? Are they model specific or a group of similar models? How much are they?

 

Rebuilding that Qjet won't be harder than any other Qjet but being a first gen model makes them problematic as they are prone to leak internally. My 66 Qjet took a ton of time and work to get straight but runs great now.

 

"Look at left rear corner of the carb and you'll see a series of numbers like 702____"

Prior to 1968, the carb number was stamped into a round tag pressed into the LH side of the carb, near the front. Color of tag and shape of hole in center also matter slightly.

You should be able to get a rebuild kit by citing any Toronado carb number from the 1966 Chassis Service Manual. What with the various oddities of the '66-only carbs, maybe you should just get a '67 Toro carb or core and use that. Linkage wise and jetting wise it will be the same as '66 Toro.

I know a guy that has several rebuilt/ core carbs of this type. A pic of your throttle arm would help, as the Toro is unique I think and with cruise may differ.

 

Here's a picture of where the early Quadrajets put the number. I've come across a couple carbs where this round disc has fallen out or been removed. The second picture is an example of that. John

Here is where the later carbs had the number stamped. I will say that I've found 1967 carbs with both styles of numbers... so I'm not sure if that was a mid-year thing or possibly different plants?
