Lars Saves the Day





I just wanted to share my experience with my carb rebuild with Lars. As most of us can attest, the man has forgotten more about carburetors, than most of us will ever know.
I emailed Lars a little over a month ago to start this process. For those of you unsure about doing this, let me tell you the process was very easy - even from a foreign country.
Lars' instructions were very straight forward and easy to follow. My carb was boxed up, as per his directions, and shipped to Colorado. I received an email about a week later, informing me that everything had arrived safely and that an initial inspection/ identification had occurred. I was also informed I was #8 in line.
About 2 weeks passed, with a few more emails to let me know I was moving up the line. This is where the story gets good......
This is a copy of the email I received from Lars the day he started work on my "original" carb that had come in a box when I bought my '79.

Brian -
I don't know how you did it, but it appears you have salvaged the original carburetor off the Titanic..! In my 35 years of building carbs, and after having built over 700 Q-Jets, I can say without any doubt that this is hands-down the worst carb I have ever seen. I've never seen one so corroded and so messed up by a commercial builder. I had to disassemble the carb with a torch, a grinder and a cutoff wheel. Parts of the carb were so corroded that they were actually gone, with only small rusty remnants left of the original parts. Here is a breakdown of the issues:
First, this is a commercially rebuilt carb, and is not the original carb off your car. This carb could never have run with the setup the way it was, even if it was not corroded beyond usable condition.
Extreme corrosion, resulting in all hardware and parts being seized and rusted in place
Inoperable accel pump - collapsed
Seized choke pulloff - inoperable
Plugged fuel filter
Inlet fitting double-gasketed
Secondary fuel feed tubes removed from airhorn and installed in incorrect, blind-hole locations - no secondary fuel flow through carb
Incorrect float installed
Extreme low float level
Extreme low APT
Power piston jammed in bore - inoperable
Power piston corroded away - destroyed
Power piston spring corroded away - destroyed
Choke housing fast idle cam pivot casting corroded away - housing destroyed
Float clip installed backwards, jamming needle in seat
In addition to the base fee, this carb will need the following items as a minimum.
Choke housing with components
Misc. Hardware
Power piston
Power piston spring
Acid dip fee - materials
The carb is in the hot-tank right now, and will hit the acid bath next in order to get some of the rust and zinc oxide off the component parts.
I'll keep you posted on results...

Now, after having read that, I thought all was lost, but I'm happy to say the carb arrived today with a clean bill of health. A detailed report showed the carb to be working perfectly and now I'm just waiting for the snow to finally melt so I can start to put some mileage on the car this summer. I am forever indebted to Lars for his help in resurrecting another quadrajet, and highly recommend his services to anyone here who may be having carb issues.

I was getting ready to send my "box-o-carb" down a couple of years back but with Lars' help (emails, post, papers, more emails, etc) actually managed to get it running and tuned to actually run and function properly (choke, secondaries etc).
I'm still temped to send it off just to see how close I ended up (I need to find better ways to spend my days)
The old distributor might be another story....

Ya know I'm kicking myself buddy that I didn't take any before........but actually the initial overall appearance didn't look too bad. I've seen much worse for sale at swap meets - even Lars' initial inspection stated " original carb in good condition". Obviously the internals told a different story. Lars mentioned that with the acid dip I might loose some of the finish, but truly she looks good my friend.
I'll try and post up some pics later today, just got back into town, work had me in Windsor for the past few days.

EVERY DISTRIBUTOR SHOULD HAVE THE LARS TREATMENT!





Your secondary airvalve baffle has been smashed during shipment - remove it, straighten it out, and re-install it.
Also, in the last photo, are you holding the airvalve open with your finger for the photos, or is the airvalve sticking open...? I hope you're holding it open...
I do wish I had taken a few shots if that thing prior to the rebuild - it was shocking enough that people stopping by the workshop were actually commenting on it and asking what I intended to do with "that parts carb." It still doesn't look good enough to be bragging about, but at least it was running well on the test stand.
Thank you all for kind comments and words - always appreciated.
Lars

thanks for catching the baffle, I'll look at it this afternoon. Also, yes I was holding the airvalve open just to take the picture........everything is snapping back just as it should. I'll send you an update in 3 or 4 weeks once all this dam snow leaves and I can get the car out.
