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
