Title: Cannot Locate Casting Number
Post by: my71olds on April 14, 2013, 06:34:38 PM

Hello:

Just pulled the Qjet from my 71 olds cutlass and I cannot locate the casting number.  Can you tell me with a picture where it should be? Also do I need another number in order to get a rebuild kit or parts.

Thanks

 Welcome to CHP!

 Should be located on the drivers side. It is on a flat "pad" near the rear of the carb.

 And with the casting number, give it to Cliff and he will have the kit you need. :)

Thanks for the info but I was looking at Cliff's website and supposedly mine would be on a circle tag next to the large QUAD sign.  I have nothing there.  Also it should start with a 7?

A 71 Olds carb would be stamped vertically on the main casting, drivers side, just above the secondary throttle shaft.

 As I said above, look near the rear of the carb. It should be there.

I apologize in advance for the gold paint:

You can see the casting number on the wall of the main body just behind the secondary throttle linkage in that photo.

Yup. Looks like it's for a 73 455.

 Nope. 1973 Oldsmobile 350cid A/T.

You're right. My bad.

There are a lot of misleading ebay sellers out there. :(

So is it any different than a 71 350 with AT?  Trying to decide to rebuild this one or not?

 I don't know why it would be any different.

The only reason to go with another carb of that vintage is if you were trying to go for a #s matching resto. Otherwise, I'd just set up what you have and tune it to run well.

 The stock specs of that carb used Primary Jets .069, Primary Metering Rods 53C, Secondary Hanger K, and Secondary Metering Rods CK.
