Carter Thermoquads ~ 'More General Information'
secondary discharge bars/nozzle showing unevenly drilled holes for discharge. I believe they can at least be made even both sides in number of holes and size, if the carb is on an aftermarket hi-perf aluminum intake manifold, tunnel ram, high rise, etc. the emulsion tubes for secondary jets on each side, with the .034" holes drilled through them.
etc.
