THE REBUILDING PROCESS

Phase I Rebuilding
  • The carburetor is disassembled and inspected. At this time problems can be observed. All threads are checked.
  • The unit is placed into a spray wash cleaner. The next step is an ultrasonic cleaning.
  • The clean carburetor is air blown dry.
  • The main body and base plate are then surfaced. The boosters are inspected for tightness and cracks. Air bleeds are sized per customer engine specs. The power valve channel in the body is machined for clearance.
  • Base plate mounting holes are enlarged to give proper main body alignment during final assembly. The base plate receives a bushing set if needed. The proper butterflies are installed. Throttle shafts are checked for wide-open position.
  • The metering block is checked for straightness. The part is spot faced and pressed flat if needed. The idle and emulsion bleeds are sized per customer engine specs. The power valve channel is also sized. Jets and power valves are selected then installed.
  • Float bowls receive the necessary float, needle & seat and accelerator pump assembly.
  • Final assembly begins with the main body installation onto the base plate. All new screws are used. The unit is then checked on the Flow bench. The airflow through the venturi as well as the signal draw on the main jet is measured. Boosters are then moved into the best possible position. Epoxy is added to the boosters for safety and stability. This step is only completed if rules allow.
  • Next the metering block and float bowl are installed. All external adjustments are made.
  • The unit is then set on the test motor for an engine check. On the motor the carburetors run to check idle and throttle response. After the test each carburetor is drained of fuel.
  • After the engine test lubricate is sprayed into the float bowl. All external screws are torqued to factory specs. The carburetor is then ready for shipment.

Phase II Rebuilding
