Just some notes on carburetor kits.
In recent years the quality of aftermarket kits has continued to decline. Most of the companies that produced rebuild kits have either went out of business or been bought up by larger companies. We noticed a change in the contents of the various aftermarket kits. 10 years ago, you could buy a NAPA kit for example, and still get OEM quality components in that kit, including the correct needle/seat assembly, complete accellerator pump, etc. This no longer holds true today, as any kit purchased over the counter will be full of generic components. Many kits still do NOT contain the correct accellerator pump, or even have an ethanol resistant flourostomer seal on it. The life expectancy of the black seal can be as short as 30 minutes when exposed to currently available modern fuel "blends".
Over the counter kits are also very limited on parts, basically just supplying a few small parts, gaskets, pump or pump seal, and a needle/seat assembly.
For these reasons, we started offering our high performance rebuild kits. They contain many parts not found in any other kits, which we consider necessary for a successful carburetor rebuild. We also include tuning parts, such as idle tubes and a power piston spring selection.
Here is a basic list of what is found in our kits. Pretty much everything except for jets, metering rods, and the choke pull-off, which are available separately.
HP .135" needle/seat assembly. We include the "windowed" seat, and will substitute any seat diameter from .125 to .149" per request.
HP accellerator pump assembly. We include the later model pump with garter spring and flourostomer seal. This keeps the seal in constant contact with the pump bore, and the seal will not swell or shrink in contact with modern fuels.
HD accellerator pump duration spring, and matching pump return spring. These components are made to our exact specifications, for optimum fuel delivery from the accellerator pump assembly. The pump retainer is also included.
Power piston springs. We include 4 power piston springs, made to our specifications, they are color coded for easy identification, and will cover any engine cid/compression/camshaft combination(s).
Secondary plastic cam and spring. Two items that should ALWAYS be replaced for any level of rebuild.
Secondary throttle shaft return spring.
Fuel filter spring.
Fuel filter.
Complete fastener set, including a 3/8"-16 set screw for the APT hole in later APT carburetors for easy external access to the adjustment screw. We also include a #4-40 screw that can be added to the airhorn to make the airflap angle adjustable.
Gaskets. We include high quality gaskets, including a 1/4" thick carb to intake gasket, and an airhorn to air cleaner base gasket.
Small parts, check ball, clips, filter housing gasket, seals, etc.
Vacuum hose for the choke pull-off.
Idle tubes. They are .034" standard, we will pre-drill them to any size required upon request.
Float. We include the correct float for the carburetor number. These are the most modern version of the nitrophyl floats, which will provide the best fuel control for all applications.
We can add jets and metering rods to your order. Currently, we have custom primary metering rods for the later APT carburetors only. We are having primary rods made for the early carburetors, and custom secondary metering rods. We should have samples in any day, and hope to be stocking them within a few weeks.
In addition to kits, we sell many other parts, including choke pull-offs that have been discontinued for some time. We are stocking the Pontiac Ram Air pull-offs with two fittings, the 73-74 Pontiac pull-offs, and the recently discontinued 71-72 Pontiac/Caddillac/Buick pull-offs.
We also have the linkage from the pull-off to the secondary airflaps, and several fuel filter housings.
We sell some of the items listed above separately from our kits. Orders for kits and small parts need to be taken over the phone. If we don't answer, leave a good number and message, and we will call you back.....thanks.....Cliff

what about striped filter threads
-
We are able to install heli-coils into the 1971 and older carburetors that used the 7/8"-20 threads. The cost is $45 plus shipping.
We do not have a heli-coil tap or inserts for the later carburetors with the 1" threads......Cliff

so ,,,i have to think up my own fix ;D,,,, ;D

How much do you get for your rebuild kits for a 17057204--replacing the nitrophyl float with a brass float? Also, how much do you get for your choke pull-off for the same carb? Thanks.
-
Most of our HP kits are $79.95. The exceptions are a few of the later computer controlled units. We include the latest design nitrophyl floats, zero problems with them. So far ethanol or any modern fuel blends haven't caused any issues that we know of.
The brass floats are OK, but lack the bouyancy of the nitrophyl floats, and many end up leaking at the soldered joints/seams, and sink to the bottom of the fuel bowl. If a brass float is used, we always submerg it in warm water and check for a stream of bubbles indicating a leak.
The choke pull-offs we use for the later carburetors have a straight fitting for easy access to the restriction. This makes them easy to modify for opening rate. They are $28.....Cliff

Do you have the linkage from the pull-off to the secondary air flaps for a 17059065? And if so, how much does it cost? I bought a carb off the internet, and realized when it got here that the linkage was missing, and did not know if it was cheap enough to replace, or if I should just look for another core. Thanks.
-
Yes, we have both the early and late linkage new, they are $8 each. That part number sounds like a service replacement carb, I would need a pic of it to get the correct part....thanks....Cliff

Here is a pic of the side that the seller used on eBay. I will try and get a better pic that zooms-in just on the choke/air flap assemblies. Most of the pics I see in your book, and on google image searches, show the tab on the air flap as slotted on later model carbs with a front pull-off. This carb just has a circle hole in the tab on the air flap connector, like I see on pics of early carbs and rear pull-off carbs, so I am wondering if someone has mixed and matched parts on this one.
-
that carb looks rough here

Up close, it is actually a decent core, if it is not pieced together as I now fear. The seller only halfway cleaned some pretty heavy grease off, so it looks splotchy in the picture. I am gonna try and take a better pic of the linkage/pull-off tomorrow.

that is a better pic,,,is the blueing from heat ??

That model does not use a link from the primary pull-off to the secondary airflap. It uses a secondary pull-off with two links, one to unload the choke, and one to the airflap linkage.
I have the links in spare parts, used, removed from cores. We always convert them to front pull-off by replacing the secondary airflap shaft and installing a stop for the airflaps.....Cliff
PS: the carb has the wrong fuel filter housing installed on it...
-
I think I may just look for another core. I didn't pay a whole lot for this one, and I can probably find one pretty cheap that uses a factory, front pull-off. I can take it as a lesson learned: When buying something on eBay, examine the pictures closely to make sure all parts are present. :-\

hey you have one for another project
-
It's very difficult for the average carguy to know if the carb is correct or complete. So many differences...Best to ask for help. Or only pay as if its a core if Pics are not conclusive..
Like Comp said. "It's a project!" Rebuild that puppy anyhow. ;)
Maybe someday we can create a photo library of the common differences / proper carb-year applications of Pull offs and throttle brackets..
Those seem to be the things that get changed more often?
-
Cliff,
I read in another post you mentioned smaller main air bleeds on Chevy carbs. Do you have parts for that?? How much??
-
Yes, we include screw in removable airbleeds with our kits for Chevrolet quadrajets that used the large main airbleeds.
The airhorn and main casting must be tapped to install them, about 3 to 3 1/2 turns with a starting tap, just enough so the airbleeds screw in flush with the castings......Cliff

Cliff If am am going to drill out my plug myself . What size should I drill the hole to and what size bolt do you use so I can cut some down at my work. Thanks
Casey ;D

I have a 1979 Corvette automatic with carb number 17059216. I need a kit for best performance. Engine is stock. Please advise price and time.
Also, I need bushings for the throtle shaft. I have the tool.
