My Rochester Quadrajet needs the following work:
1)  Fix the damaged threads on the fuel inlet.
2)  Spot-face the gasket sealing area on the fuel inlet (there is s slight nick in it currently).
3)  Install bushings in the primary throttle shaft bores to get rid of shaft play.
4)  I would also like to have the correct green Teflon coated shafts re-installed in the carburetor.  The originals were sandblasted & plated by a previous restorer, and I would like to get it back to being as correct as possible.
5)  I would like to send the carburetor out to someone who can perform this work and give the old q-jet a once-over to ensure that it is in proper working order. 

Right now, I am considering the following restorers:
1)  Cliff's High Performance (www.cliffshighperformance.com)
2)  Jim McGowan / The Quad Shop (www.thequadshop.net)
 
Does anyone have any recommendations or feedback on these shops?  Whoever I send it to will need to be able to source a set of good original condition correct green shafts.
Any recommendations would be greatly appreciated.
Thanks.

Jeff, Eric Jackson completed a tri-carb holley set up (Corvette) and recently restored our 68 Z/28 holley carb. He does just outstanding work. If you check the chevelle and camaro.net, and corvette forums his name is one of the first one that comes up and I have never read anything negative about any of his work. I sure liked what he completed for us and his excellent reputation for quality work speaks for itself. I know he does quadrajets so you might want to give him a call and ask him about what you want completed. Here is his website:

Good luck!

Haven't researched it yet, but maybe you can re-green your own shafts  Smiley
Down the page it says 'High build green.........carburetor shaft linkages'

Sure is hey!!  Smiley

There's also some interesting plating kits here that I'm having a close look at.
http://www.caswellplating.com/kits/index.html

There's an agent here in Australia and I might try the blackening [black oxide - parkerizing] kit to blacken bolts etc.
Not cheap though and being chemicals the postage is quite hefty, in fact for me at least, I'm better off to get a couple of different kits [at least] as the postage is almost the same.

I had a long conversation with Cliff, and it is very apparent that this guy is truly a Q-jet expert who is very detail-oriented.  He was surprised by some of the things done to my carburetor during a previous restoration.  So, my Q-jet is all packed up and heading to him later today.  He has a lot of used parts available so he is going to try to find the parts to make my carburetor 'correct' again.  Luckily, I took many detailed photos of the carb in its original state, so they will help get the carb back to original. 

As for the Green teflon-coated shafts, he's going to see what he has for used ones but it is unlikely that any used shafts will be good enough to put on the restored carb.  The good news is that he can replicate the green color on the exposed areas of the shaft with a baked-on enamel.  I have asked that this be done to my carb.

Who else provides Quadrajet restorations out there?

There must be more people out there providing correct services for restorations.

I thought that Eric J did not do Quadrajets anymore? Huh

Seems there "might" be a few out here in SoCal.

I am going to speak with a guy here in OC later this week or next.

I want to speak with him and see his work prior to my first carb with him.

I'll keep you posted.

I was reading a somewhere online that is suggesting that the throttle shafts were teflon coated?

Can there be more discussion here as to known knowledge for replatings, coloring, and correctness here regarding restoring QuadraJets?

I've been holding out on restoring my original carb because I wanted to get the job done right by the right shop the first time.

I just looked at Eric's website. It is indeed posted there that he is still doing QuadraJets.

Just wanted to update and clarify this for him and everyone else interested.

I just got notice today that Cliff has my carb stripped down and he has identified all the work that needs to be done.  Yes, it's been a while since I sent him the carb, but I knew that he had a 6-8 month backlog when I sent it in.  I gave them the go-ahead and it should be done within the next week or so.
I'll try to post some pictures when I get it back.

There are plenty of carb people around. I would not put up with anybody keeping my carb over a couple weeks. They are really not rocket science whether it is a Holley or Q-Jet. I bet Jerry M. wiould have it back way quicker than that. Most of the times I think these carbs come back over colored/restored anyhow but that is JMO.

Yes there are.  However, it seems that only a few actually know what they are doing.

Yeah, he turned mine around fairly quickly.  But it was far from "mine" when it was returned to me, and it wasn't properly restored.

What Jeff states here is not totally true.  I tried to go the extra distance with him but he was still not happy.  I did do my best, my plater was partly to blame and co-mingled some small pieces by mistake, I had also tried to make it up with a discount with a future dist job and refunded money on the carb job. 

He did get HIS carb back and it tested well and ran fine.  There were very anal issues about the plating on the shaft.  I explained that plating the shafts removes the green teflon coatings, etc.  It's water under the bridge.  I have improved some of our steps to the plater so these issues never happen again........I did the best I could for the man.  That's all I can do.

I should also mention that I did a Q-jet and engine reebuild job for a retired secret service agent.  He was very anal and could not have been happier with our work.  He also wanted to make his L35 396 SS396 Camaro make over 400 hp and still retain all stock parts.  A challenge to say the least.  The results were 405 hp with stock Q-jet carb, cast iron intake and stock L35 engine with slightly larger camshaft.  A very tall order to fill but we did it.

We all know that you can't please everyone, especially in business, but with that in mind, I will say that I just had my Holley restored by Jerry and was VERY pleased with the results. Since I drive my car and don't care about plating, colors, correctness, etc... I just wanted him to "rebuild" it and test it for me to make sure it was working correctly. However, after I got it back, it was absolutely beautiful and "restored". Almost too beautiful to install on a driver!

So yes, there will always be customers that will never be satisfied with the results, but there will also be others like myself that couldn't be happier.

OK, my original post asked for experience with 2 specific shops that rebuild Q-jets.  Neither shop was CHP.  When sam inquired about CHP (Jerry), I simply stated that previously my carb wasn't properly restored by them.  That's a fact.  Did my carb look good?  Yes, it sure did.  Was my carb restored properly?  No.  Following the rules of the forum, I made a factual statement that was by no means intended to start an argument.

The interesting thing here is that if I made this statement about any other vendor, nobody would care.  Unfortunately, CHP/Jerry have a reputation and a big "fan base" built up here.  Everyone wants to come to his defense.  

Then there's the stories that follow about how happy people are with his work.  That's great - for those people.  Oh, and some of these people aren't just normal people like us, they're super-special people like a retired secret service agent.  Wow, indeed.  They're not regular people like me - heck, I'm only a Mechanical Engineer with almost 20 years experience and multiple international patents who's been working on cars since I was in elementary school, what would I know?

Now, show me the proof that what was done by CHP was a correct restoration.  Show me the before & after hi-res pictures documenting the correct components were used.  What?  There are no pictures?  You have no idea where your original factory-correct components are?  Wow, what a surprise.  The fact is that I have a bunch of pictures and would be more than happy to point out everything that was done incorrectly to my carb.  But, again, my intent was not to start an argument so I'm not going to get into any more details (yet).

Jerry-
Please go back and read this:  http://www.camaros.org/forum/index.php?topic=7631.0
Stating that what I said was "not totally true" is the same thing as calling me a liar, and that's the best way to start an argument.  Arguing doesn't belong here.

So, please go back and read what I wrote.  My statements were:
1)  That my carb "...was far from "mine" when it was returned to me, and it wasn't properly restored."
2)  "No, he didn't."  in response to sam's statement that "I am sure he will do good for you."
These are both completely factual statements.

Now, Jerry, do you want to continue?  If so, then the gloves will come off.  If no, then I suggest you go back and edit your posts (or contact a mod to have them edited) and we'll make it like none of this ever happened.  How about you plan taking care of this by, say, 9am tomorrow.

To everyone else:
I'm sorry to have to make a post like this.  It's not really my style for these forums.  I have made some simple factual statements about MY experience with this vendor.  I was not trying to start any type of argument, but when bit I will bite back.  I'm not scared or intimidated by anyone's reputation or supposed expertise.

OK, here we go.  First thing to remember is that all this happened almost 4 years ago.  Notice that I never started a thread to post my issues with Jerry to try to warn everyone.  I kept these issues to myself.  Unfortunately, Jerry has decided that he wants to revisit this in a public forum.

Here’s what happened:
1)  I sent Jerry an all-original (other than gaskets) Q-jet from a 68 L30/M20 convertible (a fairly rare car).  The carb was in great shape, but had been sitting for a while.  I fully documented the carb with hi-res photos before it was sent.

2)  The carb was sent to Jerry with written instructions that the fuel inlet threads be repaired and ALL original parts be returned to me.

3)  When my carb came back, it did not have its original hardware, fuel inlet, and several brackets & linkage pieces were not the originals.  The fuel inlet threads had not been repaired as requested.  My nice condition original white stripe actuator hose had been replaced with some cheap parts store hose.  All exposed hardware was very loose.  Mismatched hardware was used for re-assembly.

4)  Only a few parts were originally returned with the carb, and almost all of these parts were not mine.  My original vacuum actuator was smashed.  

***I called Jerry.  At this point, Jerry’s excuse for the different parts on my carb was that all these parts required replacement because the originals were not usable.  Nothing about a mix-up at the platers.  Remember that.

5)  Since I requested that all parts be returned to me, I gave Jerry the opportunity to make things right by simply finding my original parts.  That’s all it was going to take to make things right.  Jerry stated to me that he would find & return my parts.  I provided hi-res close-up photos of all my parts to Jerry so he could track them down.

6)  I received a bag full of carb parts from Jerry.  Only one of these parts was mine.  The rest were not mine.  Many parts were still missing.  To me, this was an attempt to fool me.  It didn’t work.  

 *** Here is where it gets interesting.  Jerry used a mix-up at the platers as an excuse in his above post.  His first excuse to me was that the parts needed replacement (see 4) above).  Now came the second excuse.  This is a note from Jerry that was sent with the parts returned per 6) above:



Pay attention carefully here.  In this note, Jerry is stating that he knowingly uses parts from other carburetors because it saves time.  This was no mix-up.  This was on purpose.  In his above post he makes it seem like the situation with my carb was not fully under his control, but it most certainly was.  Jerry is misleading everyone here and trying to use his reputation as a shield.

7)  My fuel inlet was still missing.  Jerry was contacted via e-mail and he stated “I will find yours but I need time to do so.”

8 )  Here are some of the other excuses given to me by Jerry via e-mail:  “Because of the diversity in my business and the extensive traveling that I do to inspect cars, work on the judging manuals, be a part of CRG, write books and field calls and questions all day, it's very difficult to get everything right 100% of the time.”  That’s the same thing as telling me ‘I’ve got better things to do’ or ‘I’m not really paying full attention to you job’.  To try to use any of these excuses should really give you an idea of how CHP operates.

9)  Jerry returned a fuel inlet fitting to me but, again, it was not my original part. This was yet another attempt to fool me by sending me someone else’s part.

10)  I was informed by Jerry that he couldn’t find any more of my original parts and they were all lost for good.  I can only imagine where my beautiful condition original parts are now.  I have a few ideas, but I’ll keep them to myself.

11)  I contacted Jerry and asked for compensation for all of my lost parts.  As a man who knows the importance of correctness and matching numbers (especially on a low production car like an L30/M20 convertible), Jerry would certainly compensate me fairly for this ‘restoration’ gone wrong, right?  Keep reading.

12)  I received $50 from Jerry.  That’s right, $50.  It was like a slap in the face.  I contacted jerry to let him know what I thought.  It was like pulling teeth to try to get any more compensation from him, and what I eventually received was insulting to me.  Yes, he did offer me a break on future work, but that’s worth nothing to me.  

These are the FACTS.

I received my carb back from Cliff and it was worth the wait.  It looks great, and it is back to having all the correct numbered parts, along with correct hardware.

And, look carefully at the pictures and you will see GREEN SHAFT ENDS!!!!!!!!!!
Now, it isn't the original teflon coating, but it is a green paint that Cliff had matched to an original shaft.  Now THAT is attention to detail.

...and just in case anyone was wondering, here are the major issues that Cliff found with my carb:
1)  Huge fuel leak at inlet nut gasket
2)  Warped main body & airhorn
3)  Bottom plugs leaking
4)  Secondary air valve shaft incorrect
5)  Primary throttle shaft bores worn

Remember, nothing had been done to this 'restored' carb after I received it back from CHP. 
It had simply been put in a box and kept in climate controlled storage before it was sent to Cliff.

Jeff,

Great looking carb.....

You didn't ask, but I would use small diameter washers on the front mounting bolts that will keep the upper body from deforming when you tighten the bolts down.
The bottom of the bolt heads eat into the metal which gouges the heck out of upper body.

^Yes, I noticed that as well.  Thanks.  Interesting because the carb has only been on and off the car a few times total.  I have a few flat washers that I picked up a while back to use under the bolt heads.
