What’s this QJet Worth
I acquired a 68 QJet Part Number 7028262 B8 VC - originally thought it was a 69 and planned on keeping it for the bird. It was in operating condition when I received it a couple of years ago. All linkage moves freely. What’s she worth?

Your carb is a "remanufactured" Frankencarb with a Carter made 7028262 float bowl and Buick airhorn and Buick throttle plate.
These kind of carbs usually have issues that takes a book to describe. Value is in individual parts if you know what to look for, as a carb next to nothing i´m afraid. |

Thanks- look forward to additional responses. Educate me - how do you know it’s a mix of parts?

Well, LOTS of tell-tale signs of being a miss-match of parts. Buick throttle shaft/baseplate. Buick choke parts, 3/8" PCV vacuum tube used as a front vent. 2GC check ball retainer driver into the hole at the top of the choke tower in the airhorn.
It's also a Carter casting, not Rochester. They don't hold up quite as well from that time period and almost 100 percent of them will need a heli-coil for the fuel filter housing and many have already had the dreaded double "O" ring N/S instead of the screw in varity. I wouldn't even work on those here when I still had the shop open doing carburetors. Lessons in humility await those who venture in that direction.......FWIW

Thanks .
I was planning on rebuilding this 17058241 carb - is it a mix of parts as well?

I don't know how to recognize the Frankencarbs like Kenth and Cliff but I can tell you that it's a Buick carb. At least the throttle plate. They have that funky, bent looking throttle arm. Actually, I would think that would be a pretty good one to build according to one of Cliff's recipes. I have one on the shelf myself. One good thing is the inlet being on the front like Pontiac.

It looks about as original and unmolested as they come......

Great - thank you. It moves freely- once I get an engine together I will contact you for rebuild kit.

What's the chance you experts could create a "How to ID a Frankencarb" sticky? I learned a little but found it frustrating when, for example, I tried to use the casting part numbers to see if the body, airhorn, and throttle plate were "correct". I never found a listing... if this exists anywhere in Rochester or Delco literature, it would be a godsend. I did learn that any carb with a blocking tab has been through a rebuilder... |

"Great - thank you. It moves freely- once I get an engine together I will contact you for rebuild kit."
Sounds great. We'll do a slight recalibration at the same time. I've built a lot of those and aside from the "goofy" linkage they make a great electric choke high performance unit.....

A better use of the casting numbers is the negative side. If a carburetor doesn't have a certain casting, it isn't what it is supposed to be; but just because it has the proper casting number is not a positive identification. A much more useful document would be a part number interchange, which Rochester actually printed........................................... .........in 1959! Have never seen a newer one. I have spent hundreds of hours, perhaps thousands of hours, working on one, but a long way from complete. Jon

I appreciate the casting numbers were machined per application and therefore not definitive. I also get your point about the "wrong" casting number being an obvious mismatch. I found it totally unexpected that each main part would not have a unique identifier after machining. I have no idea how they managed this in a factory but obviously they had a way. Interesting and again, unexpected, about the lack of a "published" interchange document. I guess without a unique identifier on the machined part, such a document would have limited value. Your list would be more like VERY valuable. I can't be the only one that's ever struggled to determine what he had or want to piece together a "correct" set of cast parts. Even being in the ballpark would feel like a home run after a couple hours of frustrating puzzle-solving. Mike |
