Default Carb Restamps

hey guys......anyone ever deal with a guy in Cal or Arizona (or both) who sells restamped carbs?

well...let's just say he might not tell you it's restamped

this brings up an interesting question. I am sure my eye is not trained, but how does one tell a restamped carb?.. if I eyeball a 200$ carb and its stamp and then eyeball a 1200 carb and its stamp.. I can see no difference.. the font and characters are spaced the same, the surface stamped is the same. I always wonder if my carb is a restamp..

as always, there is no way to prove otherwise..

Seems to be getting worse for collectors. If there's enough price boost for numbers be it serial numbers on a block or stamps on a carb, someone will do it.

If you can't tell the difference, does it matter? Maybe if the next buyer can, a bit doubtful.

If it's Qjet, I've seen the 'stamp pad' area be machined down with a new stamp added. Sometimes this leaves a sharp edge you can feel with a fingernail.

Hi,
I find the same thing as Mike.
Some are a bit obvious and some go right by my eye I'm sure.
I think it's the same as with so many other parts; the rarer the application, the more possibility there is for enhancement.
Regards
Alan

well....let's just say there is an outfit selling "clones" on some sites. Problem is that the word "clone" is used very well hidden in the middle of the description, sometimes not in the title. The carbs go out into the general public...then someday resold as "original" even if the guy who bought it is unaware.

I know some early q-jets had the circular button where the part number went and the "pad" was blank. I think what they do is to grind off the circular part and stamp the blank pad. Not sure.

Here is an example....I have two 68 327/350 hp Q-jets (7028219 DG),,,,pretty hard to come by. I had one restored and is currently on my car. The other is a core, original to the 68 I have for sale. On BOTH of these, and every other one I have seen, the number
"2" is different on the same carb...(the first 2 is different than the second 2 on the same 7028219). According to the gurus...this is correct. I saw a recent restamped 7028209 and the "2's" were identical. That was the first clue...come to find out these "clones" are everywhere.

Anyone see these on "that site" or CL?

i guess it only matters if you are paying $800 for a carb core that started out as a $25 truck carb.

Agree, that would hurt... but if you can't tell the difference, don't know what can be done. Only defense would be to learn what to look for and hope the cloners haven't caught up?

Good evening, John. I hope your theory is correct. Here is my '68 427/390 HP Q-jet (7028216) equipped with a Turbo Hydramatic 400. Like you indicated, the "2's" looks different - the first "2" is smaller than the second "2".

Hi Blair......exactly what I was talking about. The original 68 carbs I have seen have exactly what you see there. Nice carb!

Interesting. Any idea why this is? Maybe the first few digits were generic, the following were stamped when the carb was configured for a specific application?

Pardon me, John. I apologize for hijacking your thread but since I have pics of my carb posted here - Can anyone tell me what the letters "FF" means right after the #7028216??? Also, the numbers 3217, in the second photo - on the carb base, I assume is the date code - Julian calendar - 321st day of 1967 - Correct???. Thanks

I understand that the two letters are a broadcast code used internally by Rochester.

Your interpretation of the date code is correct.
