You can purchase a rebuilt carburetor for your application which will be bolt-on. It will not have the original "numbers" (unless you get real lucky), but it will be correct for your application in functional ways. One manufacturer is Autoline and their part number for the carb for your application is C9292. This carb costs about 300 bucks.

While I'm not a big fan of commercially rebuilt carburetors, new Q-Jets are no longer available.

Another option for you might be a Holley spread bore carburetor (for Q-Jet replacement). These are available new, but I'm not sure if one is made for your specific application.

Re: 1975 Carburetor Help

Paul I have used the carb Holley 6210 carb posted by Joe L. since about 1974. The 6210 http://holley.com/0-6210.asp does not have an electric choke. I bought one for my 68 and one for my 70. The mechanical choke hooked directly up to what was available on the intakes with the QJets that were on the 68 and 70 and worked fine.
The 6210 has mechanical secondarys which I like very much. Holley does sell a spreadbore with electric choke, but it has vacuum operated secondarys instead of the mechanical operated secondarys.

holley also sells electric choke conversion for some carbs so check with holley tech service if it will work on yours.

Paul, it probably would be cheaper to buy a junk carb, rob the parts you need to repair yours. I think the stove and rod are available in reproduction.

....I had a 1975 L-82 coupe for 19yrs and sold it two yrs ago, but if I remember correctly the '75 had like a "hot air box" where the old style thermostatic coil w/rod went for the choke. This "hot air box" also had a heat tube coming from it that went to the carb choke thermostatic coil on the pass side. When I purchased a rebuilt carb, it came with none of the choke parts. I had to take my choke parts(pieces mentioned above)and put them on the replacement carb. He may have to scout around for some of those original pieces in order to get one to work. I don't have any reference pics, but good 'ol eBay can be great for that even if people do try to sell phony PCV valves.

The 1975 choke set-up was as you described. I would not expect that any of the parts you mentioned would be included with a rebuilt carb. I interpreted the missing parts involved here are the choke parts which are integral to the carb. Those should be supplied with a rebuilt carb. However, if the parts you mentioned are needed, they will need to be obtained used or in reproduction, if available.

Paul,

I have a spare replacement Q-jet for '75 if you're interested. I just finished the restoration of my '75 L-48, 4-sp car and installed its original carb. Long before I caught the NCRS disease, my original Q-jet was replaced with a new one in the late-80s. Luckily I kept the original on the shelf!

If you're interested, I can get you the numbers of the carb if you want. At least it's compatible for your car. I know there is some difference between a Q-jet for a 4-speed car and one for an automatic. May be too small a difference to worry about.

Re: 1975 Carburetor Help

If it helps I think my son still has the original 1975 Q-jets off his L48 & L82 4-speeds. Maybe Joe knows of any difference in them? Anyway PM if you want to see if he still has them and he wants for them. It's probably in a box marked for Carlisle but he should be able to get to them for some numbers.

The differences between the 1975 L-48 and L-82 carburetors were as follows:

--throttle body assembly

--choke pull-off

--primary jets

--primary metering rods

--secondary metering rods

All other components were the same for each carb. Just how the throttle body assembly was different, I do not know.

Re: 1975 Carburetor Help

Joe,

What's the difference in an L-48 4-sp carb and one for an automatic?

Just curious.

I can find no difference in the components between the Q-Jet for 1975 manual trans applications versus auto trans applications. However, it is possible that some different component(s) was(were) used for PRODUCTION carbs but "consolidated" in SERVICE.
