PHOTO #1
Outlet view of 4-runner manifold, 38/38 DGAS carb with synchronous opening throttle plates with 27/27 mm main chokes. Carb has been modified to delete top choke butterflies, choke pull-off. and water heated choke thermostat. Carb was also drilled and tapped to produce fuel outlet for return to tank in order to keep fuel circulating and cool. Photo also shows 1" aluminum spacer, with phenol heat isolator. Stud holes were tig-welded and retapped/tapped to better line-up large throttle butterflies. Aluminum spacer has been blended for transition between carb outlet and manifold inlet. Manifold runner outlets have been matched to intake gasket.

Assortment of 4 additional emulsion tube sets, 6 additional idle jets, 12 additional air correction sets, and 5 additional main jets sets. If you can't tune it with this stuff, it can't be done! All jets work on either DGAS and the ADFA carbs.
