After 8 days and 60 views and no help in the Small Block Engine forum, I thought I would bring this request out to the General Discussion to see if someone out here might be able to help.

I need a picture or two of the driver's side of the carb. Specifically the area where the accelerator cable attaches to the carb and the area of the throttle return spring.

I was not able to find any good views of this area in either the CSM or the Assembly manual. Any help is appreciated.

Thanks,

 

Hi Alan
Attached are photos from my 1967 grandma car so I believe this is factory. It's an automatic car, and there's no return spring at the carb. I do see a couple springs at the kickdown switch, and when the throttle rod is pulled back the green spring does extend. If your car has an automatic I believe this is what you need. If you have a 4 speed car I'm afraid this won't help. Let me know if there's any other views you'd like to see.

Hey Hey...I see an ST300 stator switch too..YEEHAW!!!!

 

Wow, thanks 2blu442, that was exactly what I was looking for. Yes, I do have an automatic. Looks like that is the throttle return spring located there near the firewall along with that kickdown switch. Hmm, the linkage for my '68 is significantly different. Looks like I will either need to put my '68 intake on or jury rig the thing. I don't like jury rigging the throttle control, so I guess I'm looking at an intake swap. It never can be easy, can it?

 

What exactly are you trying to do? The throttle linkage on the 64-67 cars is COMPLETELY different from that on the 68-72 cars. The early cars use a solid rod linkage, the later cars use a flexible cable. The intake has pretty much nothing to do with it. Are you putting the early motor in a 68 or the later motor in a 67?

 

Alan, what about the two holes in the intake just in front of the carb. I know some of the 70-72 cars had a tab with a hook for the return spring, I think it was located in this position. Also which year of carb are you running? The 1967 doesn't have a hole to hook the spring to so one would have to be drilled. I was looking for a picture but haven't been able to come up with one.

Hi Rob
Here's the thread when I bought the car. I'm thinking of selling it now, but am afraid its worth more in parts than as a driver. John

OK, I just read your other post.

You have a couple of options here. The best solution is to install the 1968 intake and carb on the 330. The easiest solution is to rebuild the 70 carb and use an electric choke. The throttle return spring is trivial. Get an aftermaket spring and bracket that bolts to one of the valve cover bolts in front of the carb. So long as the 70 carb still has the circular choke housing, simply get an electric choke coil, such as used on the mid-1980s GM full size pickups with Qjet. RockAuto has a couple of Airtex/Wells P/N 2C1098 choke coils on wholesale closeout for $5.94 each. Wire it like this.

 

Yeah Joe, you're right, the easiest would be to rebuild the '70 and put an electric choke on it. Actually, when I bought the car it had an adapter (may have been home made) that bolted to the choke well with tubes that came up to the choke coil. Maybe I should see if I kept that and use that instead of the electric). Rebuilding the '70 is probably what I should do for this year at least. I can do that while it remains so frigid here. I've got more than enough work to do on the Starfire without throwing in an intake swap on the Cutlass. Thanks guys for all the ideas. I think I am now leaning toward the '70 rebuild, which wasn't even on my radar before I asked the question.

 

OK, I dug the '70 carb out of storage and took a good look at it (I really hadn't looked at it before as I always considered it nothing more than a leaky POS). It is a Carter Quadrajet and the info I can scrape up about it on the internets is that it started out life on a 1970 Chevy Truck attached to the top of a 402 cu in V-8 engine.

My next question: Is it even worth rebuilding this carb for my 330? If it was originally designed for a BBC will I ever be able to get it tuned in correctly?

 

The basic Qjet castings are all the same, so a simple jet and rod change will work wonders. You can swap the rods and jets out of the 67 carb, for example.

 

except chebby used huge air bleeds... chebbies like their air.

A question that has never been asked is what transmission is in the car. The one from the 67 or 68?
