Services

Each of the three base Remanufacturing Services and the Restoration Service are described in the overviews below with itemized parts and services provided in the Pricing matrix.

Level 1

Offered to those wishing to minimize their costs by performing their own disassembly, rebuilding and tuning. The following tasks are provided for the Level 1 remanufacturing service:

• Machine work for and installation of new Throttle Valves and throttle shaft bushings
• Throttle Bodies are remanufactured with the following items addressed:
  • New throttle shaft bushings installed using oil-impregnated bronze bushings (Qty = six per throttle body)
  • Honed throttle bores (to correct for wear and distortions from aging) with matched Throttle Valves
• Factory finishes restored on Throttle Shafts, Throttle Lever Arms, Throttle Return Torsion Springs, Accelerator Pump Linkage Lever Arms, Throttle Lever Arm Spacer Washers and Throttle Shaft Couplings
• Throttle Bodies ultrasonically cleaned and fuel galleries flushed
• Includes:
  • Bottom surface of Throttle Bodies re-machined for flatness
  • Throttle Shafts reworked as follows:
    • Throttle Shafts straightened for both twist and bending distortions before reassembly
    • Throttle Shaft twist adjustments performed to synchronize the two Throttle Valves on the Long Throttle Shaft with the Throttle Body transition ports
    • Long and Short Throttle Shafts axially preloaded to control Throttle Valve edge wear
    • Short Throttle Shafts re-peened to tighten end plates onto shafts
  • Throttle Lever Arms reworked as follows:
    • Straightened and de-burred
    • Slotted hole resized for tight fit with Long Throttle Shaft (Important to assure full throttle rotation)
    • New, OEM style, riveted 8mm ball studs installed
    • Adjusted to provide fully open throttle valves
  • Selected fasteners replaced (See Pricing web page for details)
  • Bench tested to assure proper closed throttle air flow
• Notes:
  • Customer to supply carburetor Throttle Bodies complete with Throttle Lever Arms. Remove all jets, screws, floats, accelerator pump components, brass bits and Carburetor Top Cover. Please review Standard Shipping Instructions provided on the Terms & Conditions web page.
  • It is assumed the supplied carburetors are serviceable units removed from a running engine. Units with missing components, seized throttle shafts, broken jet holders or that are corroded and/or dirty will result in adders in the cost estimate in order to return them to service.

Level 1A

This service is a subset of the Level 1 effort described above, the basic differences being only four shaft bushings are installed per throttle body and stock 40mm throttle valves installed in lieu of the honed and matched throttle valves. This service will in many cases result in fully functional carburetors and nearly new performance and tuning characteristics. This option is provided only with the customer's acknowledgement of the limitations of performance expectations.

Level 1B

This service is a subset of the Level 1 effort described above, the basic difference being only four shaft bushings are installed per throttle body; includes honed throttle bores with matched Throttle Valves. This service will in many cases result in fully functional carburetors and nearly new performance and tuning characteristics. This option is provided only with the customer's acknowledgement of the limitations of performance expectations.

Level 2

The Level 2 service option continues where the Level 1 effort stops and adds rebuilding and initial on-engine tuning. The result of this combination returns the carburetors remanufactured, rebuilt, tuned and ready for installation on your car. The following are additions to the Level 1 remanufacturing service above:

• Carburetors are completely disassembled excluding removal of lead plugs and studs
• Factory finishes restored on all components except: Throttle Bodies and Carburetor Top Covers (including studs)
• Complete carburetors ultrasonically cleaned, reassembled with new gaskets and tuned on our dedicated test engine; returning them ready to run
• Includes:
  • Sealing surfaces re-machined for flatness
    • Fuel Float Valve Well Hex Caps and Top Cover interfaces
    • Fuel Inlet Manifolds (Banjos) and Top Cover interfaces
    • Auxiliary Venturi interfaces with Throttle Bodies
  • Blueprinted components
    • Fuel Floats
    • Accelerator Pump Covers
    • Accelerator pump jets - individual injection volume and aiming
  • Metering screws, jet holders, etc. de-burred and plated or polished
  • Air vent pipes on top covers removed, replated and reinstalled
  • Anti-percolation holes drilled in Top Covers
  • Accelerator pump and injection system operation verified
  • Jet and venturi sizes verified
  • Fasteners replaced (See Pricing web page for details)
  • Aircraft quality safety wire installation
  • Installation gaskets included (See Pricing web page for details)
  • On-engine tuning including:
    • Fuel Float Valves shimmed on running engine
    • Idle Air Adjusting Screws, Idle Mixture Adjusting Screws and Throttle Adjusting Screws set on running engine
    • Accelerator Pump Rod Assemblies adjusted for injection volume
• Notes:
  • Customer to supply complete carburetors including Banjo fittings but retaining Intake Air Horns, air cleaners, intake manifolds and throttle linkages unless arrangements have been made for their delivery. Please review Standard Shipping Instructions provided on the Terms & Conditions web page.
  • Customer is responsible for performing final adjustments to tailor the tuning of their carburetors to their engine.
  • It is assumed the supplied carburetors are serviceable units removed from a running engine. Units with missing components, seized throttle shafts, broken jet holders or that are corroded and/or dirty will result in adders in the cost estimate in order to return them to service.

Level 3

The Level 3 service option adds restoration the Level 2 remanufacturing option resulting in completely restored carburetors both mechanically and cosmetically. All components are removed, inspected and replaced or restored. The following are additions to the Level 2 remanufacturing service above:

• Carburetors are completely disassembled including removal of lead plugs and studs
• Factory finishes restored on all components
• Carburetors ultrasonically cleaned, reassembled with new gaskets and tuned on our dedicated test engine; returning them ready to run.
• Includes detailed cleaning of fuel galleries and re-plugging
• Notes:
  • Customer to supply complete carburetors including Banjo fittings but retaining Intake Air Horns, air cleaners, intake manifolds and throttle linkages unless arrangements have been made for their delivery. Please review Standard Shipping Instructions provided on the Terms & Conditions web page.
  • Customer is responsible for performing final adjustments to tailor the tuning of the carburetors to their engine.
  • It is assumed the supplied carburetors are serviceable units removed from a running engine. Units with missing components, seized throttle shafts, broken jet holders or that are corroded and/or dirty will result in adders in the cost estimate in order to return them to service.

Restored, Rebuilt & Tuned

This option returns your satisfactorily performing carburetors completely restored, rebuilt, tuned and ready for installation on your car. The following tasks are provided with this service:

Machine work includes:

• Updating the outer throttle shaft bushings with new oil-impregnated bronze bushings; Qty (2) bushings per Throttle Body
• Bottom surface of Throttle Bodies re-machined for flatness
• Sealing surfaces re-machined for flatness
• Fuel Float Valve Well Hex Caps and Top Cover interfaces
• Fuel Inlet Manifolds (Banjos) and Top Cover interfaces
• Carburetors are completely disassembled, restored, reassembled and tuned per the Level 3 service option
