Each carburetor is completely disassembled - back to where it was in the factory before assembly.
In many cases we can loosen seized or corroded parts that can't normally be disassembled, using electrolysis or various proprietary methods.
The cast pieces are checked for warpage. Zinc or aluminum castings are trued to ensure that all parts match. Cast iron parts are refinished as required.
Zinc carburetor bodies receive the original type chromate conversion coating.
Aluminum parts are restored to natural aluminum and are treated with chromate to seal the surface for corrosion protection.
Cast iron parts are usually finished in black oxide and sealed with a clear coat to prevent corrosion, though other black finishes are available for special applications.
Steel linkage parts are plated in yellow or clear zinc as required.
Wherever possible we use new fasteners. We have an inventory of tens of thousands of original screws, from original Holley float bowl screws to a huge selection of Fillister slot screws. We even have new Rochester Quadrajet screws plated in corrosion resistant black zinc. No more chewed up, rusty old screws!
Parts like accelerator pumps, diaphragms, power valves and all other parts that wear are replaced with new or rebuilt units. Choke pull offs are new where available or rebuilt. Rebuilt choke pull offs include a new diaphragm and replated steel parts and are as durable as new ones.
Each carburetor we restore gets every new part available if needed. We try to maintain the integrity of the original unit as much as possible, but if a new part is available and is better than reworking the old one, we'll use it. The goal is to restore the original durability and life expectancy of the carburetor.
Cores and Used Parts
We have many thousands of cores and used parts to support our restorations.
In summary, our carburetors are remanufactured and restored to look and function like new.
