Absolutely correct. When I upgraded my air cleaner to a much more free-flowing cleaner I had to not only readjust the mixtures but, because the venturi vacuum was
reduced because there was more volume that was now travelling slower, I had to go to a lighter spring to have the secondaries open correctly.
